Abstract: New classes of luminescent transition metal complexes, including the systems of rhenium(I) tricarbonyl diimine, cyclometalated iridium(III) diimine, cyclometalated rhodium(III) diimine, ruthenium(II) diimine and ruthenium(II) terpyridine complexes tethered with rhodamine moieties, have been synthesized. The X-ray crystal structure of one of the cyclometalated rhodium(III) diimine complexes with rhodamine pendants, [Rh(SPLC2N2)(ppy)2](PF6) has been determined. The molecular structure of [Rh(SPLC2N2)(ppy)2](PF6) showed a distorted octahedral geometry and the rhodamine moiety was found in a spirolactam closed-ring form. All of them were found to exhibit emission in fluid solution. The emissions of rhenium(I) tricarbonyl diimine and ruthenium(II) polypyridyl complexes are derived from the triplet metal-to-ligand charge transfer (3MLCT) excited state, i.e. from dπ orbital of the rhenium(I) or ruthenium(II) metal center to the π* orbital of the diimine ligand; while that of cyclometalated iridium(III) diimine complexes is (3MLCT) [dπ(Ir) → π*(N DEGREESN)] and that of cyclometalated rhodium(III) diimine complexes involves the (3IL) [π → π*(N DEGREESC)] excited state, probably mixed with (3MLCT) [dπ(Rh) → π*(N DEGREESC)] character. The cation-binding properties of these complexes toward alkali, alkaline-earth and transition-metal cations were investigated by electronic absorption and emission spectrophotometries. Some of them were found to exhibit new low-energy absorption and emission bands, characteristic of the rhodamine absorption and emission, with high selectivity and sensitivity for certain transition metal cations. A series of rhodamine-appended Schiff base organic compounds has also been synthesized in order to explore their capability as luminescent lanthanide ion sensors. The lanthanide ion binding properties of one of the compounds in acetonitrile were examined. Upon addition of lanthanide ions, new intense low-energy electronic absorption and emission bands were also observed, characteristic of the rhodamine absorption and emission, demonstrating its lanthanide ion sensing behaviour.

This book was released on 2021 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rhodamine derivatives have been found to sense transition metal ions selectively, and the related chemosensing behavior has been studied extensively. Drastic color changes and emission enhancements have been observed as a result of spirolactam ring-opening during the stimulation of certain transition metal ions. Because lanthanide ions are known to prefer higher coordination numbers than transition metal ions, the utilization of this preference is a potential strategy for exploring rhodamine-based chemosensors for selective lanthanide ion sensing. In addition to their application as chemosensors, rhodamine organic dyes can also be incorporated into luminescent transition metal systems and function as photosensitizers for efficient photodynamic therapy (PDT). Furthermore, introducing anti-cancer drugs into rhodamine-transition metal hybrid systems can yield synergistic effect that cause tumor cell death. In this thesis, we focus on the molecular design, characterization, properties, mechanisms, and practical application of rhodamine-based chemosensors and photosensitizers. In Chapter 1, the development of rhodamine-derivative-based chemosensors and rhodamine-containing transition metal complexes is summarized. In Chapter 2, a series of rhodamine-derivative-containing macrocycle compounds are designed, synthesized, and characterized. One macrocycle compound called MR1 was determined to exhibit selective sensing towards Tb( I) and Dy( I) ions with high sensitivity. Based on binding constants and high-resolution mass spectrometry measurement results, sensing mechanisms of MR1 for Tb( I) and Dy( I) ions are proposed. Furthermore, MR1 exhibits high stability and reusability for Ln( I) ion absorption in the solid state. This is the first example of rhodamine derivatives as fluorescent probes for Ln( I) ions. The molecular i structures of the macrocycle compounds are defined as follows: In Chapter 3, a series of rhodamine-appended Ir( I) complexes with different cyclometallating ligands are designed and synthesized, and the relationship between singlet oxygen (1O2) generation efficiency and the energy level of the Ir( I)-based triplet metal-to-ligand charge transfer (3MLCT) excited state (T1') is investigated and correlated. In addition to the direct population of the rhodamine triplet excited state (T1) through the intersystem crossing process, the T1' state acting as a relay could provide an additional pathway to generate the rhodamine T1 state, leading to enhanced 1O2 generation ability. More importantly, this study provides a novel concept for the molecular design and exploration of other photosensitizers for efficient PDT. The molecular structures of rhodamine-containing Ir( I) complexes are defined as follows: In Chapter 4, the mechanism proposed in Chapter 3 is verified to be adaptable not only in an iridium( I) system but also in a platinum( ) system. 1O2 generation ability is significantly enhanced by reducing the energy gap between the Pt( )-iv based 3MLCT state (T1') and rhodamine singlet state (S1). Furthermore, the in vitro PDT effect is significantly enhanced by introducing anti-cancer drugs into a rhodamine-tethered Pt( ) system. The molecular structures of Pt5 with high 1O2 generation ability and Pt6 with the best in vitro PDT performance are defined as follows:

Download or read book Design and Synthesis of Cyclometalated Transition Metal Complexes as Functional Phosphorescent Materials written by Shuang Liu (Ph. D.) and published by . This book was released on 2012 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyclometalated Ir(III) and Pt(II) compounds are among the most promising phosphorescent emitters for various applications, such as organic light emitting diodes (OLEDs), chemical sensors and bioimaging labels. This family of complexes exhibits high thermal and photo-stability, excellent quantum efficiency, and relatively short lifetime. More importantly, their luminescent properties can be fully tunable by modifying the coordinating ligands. In this thesis, a series of 2-(1,2,3-triazol-4-yl)-pyridine derivatives, referred to as the "click" ligands, are used to build phosphorescent Ir(III) and Pt(II) compounds. The robust and tolerant nature of the copper mediated 1,3-dipolar cycloaddition reactions offers great flexibility in the molecular design. Chapter 1 and Chapter 2 focus on the synthesis of heteroleptic cyclometalated Ir (III) and Pt(II) complexes by utilizing the Cu(I) triazolide intermediates generated in "click" reactions as transmetalating reagents. Ligand synthesis and metalation can be achieved in one pot under mild reaction conditions. For the Ir(III) system, the "click" ligands show switchable coordination modes, between the C, N- and N, N-chelation. These ligands act as C, N, N-bridging units to form unique zwitterionic dinuclear complexes with two cyclometalated Pt(II) units. In Chapter 3, cyclometalated Pt(II) complexes with N, N-chelating "click" ligands are synthesized. Their aggregation-induced solid-state emission is highly responsive to environmental stimuli, such as solvents, heat and mechanical force. This family of compounds represents the first thermotropic Col(h) liquid crystals with only one sidechain. Furthermore, the combined liquid crystalline and mechanochromic properties make them attractive functional materials.

Available in PDF, EPUB and Kindle. Book excerpt: Anion recognition plays a critical role in a range of biological processes, and a variety of receptors and carriers can be found throughout the natural world. Chemists working in the area of supramolecular chemistry have created a range of anion receptors, drawing inspiration from nature as well as their own inventive processes. This book traces the origins of anion recognition chemistry as a unique sub-field in supramolecular chemistry while illustrating the basic approaches currently being used to effect receptor design. The combination of biological overview and summary of current synthetic approaches provides a coverage that is both comprehensive and comprehensible. First, the authors detail the key design motifs that have been used to generate synthetic receptors and which are likely to provide the basis for further developments. They also highlight briefly some of the features that are present in naturally occurring anion recognition and transport systems and summarise the applications of anion recognition chemistry. Providing as it does a detailed review for practitioners in the field and a concise introduction to the topic for newcomers, Anion Receptor Chemistry reflects the current state of the art. Fully referenced and illustrated in colour, it is a welcome addition to the literature.
Book Synopsis Luminescent and Photoactive Transition Metal Complexes as Biomolecular Probes and Cellular Reagents by : Kenneth Kam-Wing Lo
Download or read book Luminescent and Photoactive Transition Metal Complexes as Biomolecular Probes and Cellular Reagents written by Kenneth Kam-Wing Lo and published by Springer. This book was released on 2015-06-30 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: The series Structure and Bonding publishes critical reviews on topics of research concerned with chemical structure and bonding. The scope of the series spans the entire Periodic Table and addresses structure and bonding issues associated with all of the elements. It also focuses attention on new and developing areas of modern structural and theoretical chemistry such as nanostructures, molecular electronics, designed molecular solids, surfaces, metal clusters and supramolecular structures. Physical and spectroscopic techniques used to determine, examine and model structures fall within the purview of Structure and Bonding to the extent that the focus is on the scientific results obtained and not on specialist information concerning the techniques themselves. Issues associated with the development of bonding models and generalizations that illuminate the reactivity pathways and rates of chemical processes are also relevant. The individual volumes in the series are thematic. The goal of each volume is to give the reader, whether at a university or in industry, a comprehensive overview of an area where new insights are emerging that are of interest to a larger scientific audience. Thus each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years should be presented using selected examples to illustrate the principles discussed. A description of the physical basis of the experimental techniques that have been used to provide the primary data may also be appropriate, if it has not been covered in detail elsewhere. The coverage need not be exhaustive in data, but should rather be conceptual, concentrating on the new principles being developed that will allow the reader, who is not a specialist in the area covered, to understand the data presented. Discussion of possible future research directions in the area is welcomed. Review articles for the individual volumes are invited by the volume editors. Readership: research scientists at universities or in industry, graduate students Special offer For all customers who have a standing order to the print version of Structure and Bonding, we offer free access to the electronic volumes of the Series published in the current year via SpringerLink.

Download or read book Systematic Exploration of Indolizine-Based Small Fluorescent Molecules written by Youngjun Lee and published by Springer. This book was released on 2018-08-16 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes an in-depth study of an indolizine-based fluorophore, from understanding of its structure-photophysical property relationship to its application as a useful biological reporter. Organic fluorophores have been extensively used in the field of molecular biology owing to their excellent photophysical property, suitable cell permeability, and synthetic flexibility. Understanding of the structure-photophysical property relationship of a given fluorophore often paves the road to the development of valuable molecular probes to visualize and transcribe biological networks. In this thesis, respective chapters deal with molecular design, organic synthesis, structure-property analysis, and quantum-mechanical interpretation of unexplored family of indolizine-based molecules. This systematic exploration has led to rational development of a new microalgae lipid droplet probe, colorful bioorthogonal fluorogenic probes, and a bright mitochondrial probe, working under live cell conditions. Harnessing the optical properties of a given fluorophore has been an important topic for a couple of decades, both in industry and in academia. This thesis provides useful insights for the improvement and development of unique small fluorescent materials, or optical materials.

Book Synopsis Intercalated Layered Materials by : F.A. Lévy
Download or read book Intercalated Layered Materials written by F.A. Lévy and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Materials with layered structures remain an extensively investigated subject in current physics and chemistry. Most of the promising technological applications however deal with intercalation compounds of layered materials. Graphite intercalation compounds have now been known for a long time. Intercalation in transition metal dichalcogenides, on the other hand, has been investigated only recently. The amount of information on intercalated layered materials has increased far beyond the original concept for this volume in the series Physics and Chemistry of Materials with Layered Structures. The large size of this volume also indicates how important this field of research will be, not only in basic science, but also in industrial and energy applications. In this volume, two classes of materials are included, generally investigated by different scientists. Graphite intercalates and intercalates of other inorganic com pounds actually constitute separate classes of materials. However, the similarity between the intercalation techniques and some intercalation processes does not justify this separation, and accounts for the inclusion of both classes in this volume. The first part of the volume deals with intercalation processes and intercalates of transition metal dichalcogenides. Several chapters include connected topics necessary to give a good introduction or comprehensive review of these types of materials. Organic as well as inorganic intercalation compounds are treated. The second part includes contributions concerning graphite intercalates. It should be noted that graphite intercalation compounds have already been mentioned in Volumes I and V.
