Download or read book Dyes and Photoactive Molecules in Microporous Systems written by Virginia Martínez-Martínez and published by Springer Nature. This book was released on 2020-12-15 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of the design, synthesis, and characterization of different photoactive hybrid organic-inorganic materials, based on the combination of mainly organic molecules and inorganic nanostructures, tackling their uses in different scientific fields from photonics to biomedicine. There are many examples extensively describing how the confinement of organic compounds (i.e. chromophores, photochromic molecules or photoreactants), or other photoactive compounds (i.e.metal clusters) into several microporous systems can modulate the photophysical properties and photochemical reactions leading to interesting applications. Among (ordered)-hosts, different systems of diverse nature are widely used, such as the, the 1D- or 3D- channels of zeolitic frameworks, interlayer space of 2D-clays, the organic nanospace of curcubituril and cyclodextrins or the organo-inorganic porous crystalline MOFs systems. This volume highlights the advances of these photoactive materials and aims to be an inspiration for researchers working in materials science and photochemistry, including chemists, material engineers, physicists, biologists, and medical researchers.

This book was released on 2015 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Chalcogenorhodamine dyes bearing thioamide or amide moieties are transported at different rates by P-gp, with amide-containing dyes being transported more rapidly than the analogous thioamide derivatives. Additionally, thiorhodamine dyes with fused ring moieties at the 3-amino position have shown decreased ATPase stimulation and increased binding affinity for P-gp relative to the analogous dimethylamino dyes. Based on these results, a synthetic route toward a new rhodamine precursor with fused ring moieties at both 3- and 6- amino positions, the bis(julolidyl) xanthone (57-E), was developed. The two julolidyl moieties impart added rigidity, increased lipophilicity, and bathochromic shifts in the wavelength of maximum absorption in the resulting dyes. The thioamide- and amide-containing bis(julolidyl) selenorhodamines are more effective photosensitizers in the PDT of P-gp-expressing cancer cells, with EC50 values an order of magnitude lower than previously reported selenium-containing photosensitizers. The bis(julolidyl) selenorhodamine 6 is rapidly transported by P-gp, localizes in the mitochondria of cancer cells, and selectively photodepletes malignant T cells while sparing T cells necessary for healthy immune function. Several tellurorhodamines with phenyl, 2-methylphenyl, and 2,4,6-trimethylphenyl substituents at the 9-position were prepared and evaluated for their potential use as reversible fluorescence probes based on a Te(II)/Te(IV) redox cycle. While the tellurides were essentially nonfluorescent ([phi]FL

Book Synopsis Synthesis and Characterization of Dyes with Solar Energy Applications by : Bradley J. Brennan
Download or read book Synthesis and Characterization of Dyes with Solar Energy Applications written by Bradley J. Brennan and published by . This book was released on 2012 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sun provides Earth with a virtually limitless source of energy capable of sustaining all of humanity's needs. Photosynthetic organisms have exploited this energy for eons. However, efficiently converting solar radiation into a readily available and easily transportable form is complex. New materials with optimized physical, electrochemical, and photophysical properties are at the forefront of organic solar energy conversion research. In the work presented herein, porphyrin and organometallic dyes with widely-varied properties were studied for solar energy applications. In one project, porphyrins and porphyrin-fullerene dyads with aniline-like features were polymerized via electrochemical methods into semiconductive thin films. These were shown to have high visible light absorption and stable physical and electrochemical properties. However, experimentation using porphyrin polymer films as both the light absorber and semiconductor in a photoelectrochemical cell showed relatively low efficiency of converting absorbed solar energy into electricity. In separate work, tetra-aryl porphyrin derivatives were examined in conjunction with wide-bandgap semiconductive oxides TiO2 and SnO2. Carboxylic acid-, phosphonic acid-, and silatrane-functionalized porphyrins were obtained or synthesized for attachment to the metal oxide species. Electrochemical, photophysical, photoelectrochemical, and surface stability studies of the porphyrins were performed for comparative purposes. The order of surface linkage stability on TiO2 in alkaline conditions, from most stable to least, was determined to be siloxane> phosphonate> carboxylate. Finally, porphyrin dimers fused via their meso and beta positions were synthesized using a chemical oxidative synthesis with a copper(II) oxidant. The molecules exhibit strong absorption in the visible and near-infrared spectral regions as well as interesting electrochemical properties suggesting possible applications in light harvesting and redox catalysis.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon monoxide (CO) is a toxic gas that has been known as the “silent killer” for decades. At high concentrations, CO reacts with hemoglobin, impairing its ability to transfer oxygen throughout the body. At low concentrations, however, CO has anti-cancer and anti-inflammatory effects. CO has also been shown to increase the sensitivity of certain types of cancer cells to the reactive oxygen species (ROS) produced by chemotherapeutics, thereby reducing drug resistance. One way to deliver CO in a controlled and safe manner is through the use of photoCORMs, or photoactivated CO releasing molecules. Transition metal-based photoCORMs are a class of molecules that release CO by breaking the M-CO bond upon exposure to light. In Chapters 2 and 3, my research study the effect of ligand set variation (both electronically and sterically) around the Mn(I) metal center on the photophysical and photochemical properties, as well as the assignment of photochemical intermediate formation during visible light irradiation. In Chapter 4, we designed a system that combined photo-activated CO delivery and singlet oxygen (1O2). The photophysical and photochemical properties of two Mn(I)-based photoCORMs sensitized with a luminescent BODIPY, as well as their ability to generate singlet oxygen during visible light irradiation were investigated.iv In Chapter 5, my focus was on water-soluble 3D supramolecular coordination cages (SCCs). The internal cavity incorporated in these structures allows them to encapsulate various guest molecules. Water-soluble Ln(III)-based SCCs are scarce, and the arrangement of water molecules inside the cavity, as well as the recognition properties of the latter, are mostly unknown. The study of such interactions would be of interest to the growing field of SCCs. To this end, we designed and synthesized a water-soluble Eu(III)-based supramolecular coordination cage with the general formula of Eu2L3 and a triplestranded helicate structure. The guest binding properties of the Eu2L3 cage were studied with smaller mono- and di-cationic organic guests through 1H NMR titration in D2O
Book Synopsis Periodic Mesoporous Organosilicas by : Chang-Sik Ha
Download or read book Periodic Mesoporous Organosilicas written by Chang-Sik Ha and published by Springer. This book was released on 2018-11-07 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of the fundamental properties, preparation routes and applications of a novel class of organic–inorganic nanocomposites known as periodic mesoporous organosilicas (PMOs). Mesoporous silicas are amorphous inorganic materials which have silicon and oxygen atoms in their framework with pore size ranging from 2 to 50 nm. They can be synthesized from surfactants as templates for the polycondensation of various silicon sources such as tetraalkoxysilane. In general, mesoporous silica materials possess high surface areas, tunable pore diameters, high pore volumes and well uniformly organized porosity. The stable chemical property and the variable ability for chemical modification makes them ideal for many applications such as drug carrier, sensor, separation, catalyst, and adsorbent. Among such mesoporous silicas, in 1999, three groups in Canada, Germany, and Japan independently developed a novel class of organic–inorganic nanocomposites known as periodic mesoporous organosilicas (PMOs). The organic functional groups in the frameworks of these solids allow tuning of their surface properties and modification of the bulk properties of the material. The book discusses the properties of PMOs, their preparation, different functionalities and morphology, before going on to applications in fields such as catalysis, drug delivery, sensing, optics, electronic devices, environmental applications (gas sensing and gas adsorption), biomolecule adsorption and chromatography. The book provides fundamental understanding of PMOs and their advanced applications for general materials chemists and is an excellent guide to these promising novel materials for graduate students majoring in chemical engineering, chemistry, polymer science and materials science and engineering.
Book Synopsis Applied Photochemistry by : Rachel C. Evans
Download or read book Applied Photochemistry written by Rachel C. Evans and published by Springer Science & Business Media. This book was released on 2014-07-08 with total page 619 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applied Photochemistry encompasses the major applications of the chemical effects resulting from light absorption by atoms and molecules in chemistry, physics, medicine and engineering, and contains contributions from specialists in these key areas. Particular emphasis is placed both on how photochemistry contributes to these disciplines and on what the current developments are. The book starts with a general description of the interaction between light and matter, which provides the general background to photochemistry for non-specialists. The following chapters develop the general synthetic and mechanistic aspects of photochemistry as applied to both organic and inorganic materials, together with types of materials which are useful as light absorbers, emitters, sensitisers, etc. for a wide variety of applications. A detailed discussion is presented on the photochemical processes occurring in the Earth’s atmosphere, including discussion of important current aspects such as ozone depletion. Two important distinct, but interconnected, applications of photochemistry are in photocatalytic treatment of wastes and in solar energy conversion. Semiconductor photochemistry plays an important role in these and is discussed with reference to both of these areas. Free radicals and reactive oxygen species are of major importance in many chemical, biological and medical applications of photochemistry, and are discussed in depth. The following chapters discuss the relevance of using light in medicine, both with various types of phototherapy and in medical diagnostics. The development of optical sensors and probes is closely related to diagnostics, but is also relevant to many other applications, and is discussed separately. Important aspects of applied photochemistry in electronics and imaging, through processes such as photolithography, are discussed and it is shown how this is allowing the increasing miniaturisation of semiconductor devices for a wide variety of electronics applications and the development of nanometer scale devices. The final two chapters provide the basic ideas necessary to set up a photochemical laboratory and to characterise excited states. This book is aimed at those in science, engineering and medicine who are interested in applying photochemistry in a broad spectrum of areas. Each chapter has the basic theories and methods for its particular applications and directs the reader to the current, important literature in the field, making Applied Photochemistry suitable for both the novice and the experienced photochemist.
