Book excerpt: Long range photoinduced electron transfer between electron donor and acceptor groups is of considerable current interest in terms of strategies for artificial photosynthesis and studies regarding the redox properties of proteins. As part of an extensive study of long range electron transfer involving biopolymers, we have carried out this year investigations of the assembly of electron transfer agents in a system of model short peptides. Also studied is a polyelectrolyte that can adopt a helical conformation when electrostatically complexed with organic dye counter-ions. The principal interest in these systems has to do with the well ordered secondary structures adopted by peptide polymers, and the capabilities for synthetic modification of peptide side chains and end groups with chromophores or electroactive substituents. The present report gives a brief account of the following elements of work related to photochemical electron transfer themes: (1) the synthesis and photochemical characterization of chromophore-bound peptides and amino acid model compounds based on the amino acids, tryptophan and the spacer residue, alanine (Ala); (2) the study of binding of the cationic organic dye to a peptide electrolyte, for which cooperative dye loading and helix formation is important; and (3) completion of the synthesis of a new series of acridinium chromophores that have rod-like'' arrangements of inked aryl rings for assembly of electron donor-acceptor systems that will exhibit especially long lived charge separation.

Download or read book Photoinduced Electron Transfer in Ordered Macromolecular Assemblies. Final Report for May 1, 1988 - June 30, 2002 written by and published by . This book was released on 2005 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The final report describes studies over a 13 year period having to do with photoinduced electron transfer for active chromophores and redox agents, including assembly of the components in water soluble polymers or polypeptides. The findings include observation of long range charge separation and electron transport using laser phototransient spectroscopy. The systems targeted in these studies include peptide assemblies for which helical conformations and aggregation are documented. Oligomeric peptides modified with non-native redox active groups were also selected for investigation. Highly charged polymers or peptides were investigated as host agents that resemble proteins. The overall goal of these investigations focused on the design and characterization of systems capable of artificial photosynthesis.

Book Synopsis Synthesis and Characterisation of Non-Fullerene Electron Acceptors for Organic Photovoltaics by : Sarah Holliday
Download or read book Synthesis and Characterisation of Non-Fullerene Electron Acceptors for Organic Photovoltaics written by Sarah Holliday and published by Springer. This book was released on 2018-03-22 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reports on the design, synthesis and characterization of new small molecule electron acceptors for polymer solar cells. Starting with a detailed introduction to the science behind polymer solar cells, the author then goes on to review the challenges and advances made in developing non-fullerene acceptors so far. In the main body of the book, the author describes the design principles and synthetic strategy for a new family of acceptors, including detailed synthetic procedures and molecular modeling data used to predict physical properties. An indepth characterization of the photovoltaic performance, with transient absorption spectroscopy (TAS), photo-induced charge extraction, and grazing incidence X-ray diffraction (GIXRD) is also included, and the author uses this data to relate material properties and device performance. This book provides a useful overview for researchers beginning a project in this or related areas.

Book Synopsis Photoinduced Electron Transfer in Binary Blends of Conjugated Polymers by :
Download or read book Photoinduced Electron Transfer in Binary Blends of Conjugated Polymers written by and published by . This book was released on 1996 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report the first observation of photoinduced electron transfer between two pi-conjugated polymers in binary systems. Picosecond transient absorption and fluorescent spectroscopies of mixtures of n-type (electron accepting) poly(benzimidazobenzophenanthroline ladder) (BBL) and p-type (electron donating) poly(p-phenylene benzobisthiazole) (PBZT) evidence intermolecular electron transfer when BBL is selectively photoexcited. The results suggest that blends of pi-conjugated polymers are supramolecular materials which have novel features such as delocalized radical ion pairs or diion pairs, novel properties, and implications for organic p-n junction devices, photodiodes, photovoltaic cells, photoreceptors, and molecular electronic devices. Observation of photoinduced electron transfer between the components of the binary blends also implies molecular level miscibility of the blends.

Book Synopsis Photoinduced Electron Transfer by : Marye Anne Fox
Download or read book Photoinduced Electron Transfer written by Marye Anne Fox and published by . This book was released on 1988 with total page 820 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electron transfer reactions are of great importance to nearly every subdiscipline of chemistry. The simple transfer of a single electron has been shown repeatedly to be a common activating mode for organic, inorganic, and biological molecules, and the very ubiquity of such reactions has guaranteed that their investigation would involve the most fundamental questions of modern chemistry. The fact that photoexcitation induces enhanced redox reactivity via electron transfer also provides a convenient method for experimentally testing theoretical predictions regarding structural and energetic effects. As can be seen from the very size of this work there is a great deal known about photoinduced electron transfer reactions and the editors have tried to capture the diversity and excitement inherent in this broad field. The reader will find contributions from theorists and experimentalists, from organic and inorganic chemists, from the perspective of the synthetic and mechanistic viewpoint. Some contributions are fundamental basic research, while others clearly show practical applications of these principles.These volumes are intended to serve a joint purpose: as a reference resource and an introductory overview to the diverse research accomplished via photoexcitation of electron donor-acceptor systems. The information is organized in four parts. The first deals with the theoretical and conceptual factors which influence electron transfer. The second covers experimental methodology and medium effects. The third and fourth deal with reactivity, with most organic transformation being addressed in Part C and most inorganic reactions covered in Part D. Each part thus provides an overview of typical reactions observed for these classes of compounds. Part D also provides examples of photoinduced electron transfer in current use in important applications. There is of course a significant interdependence between the four parts. Subject, chemical, and author citation indices appear at the end of each of Parts A, B and C, and comprehensive indices are included in Part D.
