Book excerpt: The dispersion of third-order nonlinear coefficients chi-3 1133 and chi-3 3333 of three different NLO(nonlinear optical) polymer films were determined by electroabsorption spectroscopy. The first material investigated is an epoxy-based polymer BP-2A-NT, with azobenzene NLO chromophore 4-((4- NITROPHENYL)(AZO)PHENYL)AZO)aniline in its side chain. The other materials are two polydiacetylenes, poly(BPOD) and poly(4-BCMU), in which the delocalized polymer chains contribute to the third-order nonlinearity. The complex spectrum of chi-3 3333 of each material is very similar in shape to corresponding chi-3 1133 spectrum. The ratio of chi-3 3333 to chi-3 1133 is 3.2 for BP-2A-NT, 1.5 for both poly(BPOD) and poly(4- BCMU). These ratios indicate that the distribution of the side-chain NLO chromophores of BP-2A-NT is very close to three-dimensional isotropy, and the distribution of the main-chain chromophores of poly (BPOD) and poly (4-BCMU) is concentrated on the film lane.

Book Synopsis Electrical, Optical and Magnetic Properties of Organic Solid-State Materials IV: Volume 488 by : John R. Reynolds
Download or read book Electrical, Optical and Magnetic Properties of Organic Solid-State Materials IV: Volume 488 written by John R. Reynolds and published by . This book was released on 1998-05-06 with total page 992 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book shows that research involving electrical, optical and magnetic properties of organic solid-state materials continues to grow both in scope and technological importance. Early studies of charge transport in conducting polymers have evolved from the elucidation of fundamental structure/function relationships to applications such as batteries, simple electrical devices such as diodes, chemical sensors, antistatic coatings, microwave and millimeter wave-absorbing materials, and photochromic devices. A particularly exciting evolution has been the discovery and development of organic light-emitting diodes (OLEDs) which appear to be nearing commercialization in an amazingly short period of time. This application is of particular interest because both electrical and optical properties must be considered.. Topics include: organic light-emitting materials and devices; photonic materials and devices; conducting and electroactive polymers and materials; molecular and supramolecular engineering; organic metals and magnetic materials and poster presentations.

Download or read book A Relaxation Study of Poled Nonlinear Optical Polymers by Infrared Reflection-Absorption Spectroscopy written by and published by . This book was released on 1993 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relaxation of poled nonlinear optical (NLO) chromophores in polymer films was characterized by infrared reflection-absorption spectroscopy. Both a guest-host system and a photocrosslinkable polymer system were investigated. Polymethylmethacrylate (PMMA) doped with either 2-methyl-4- nitroaniline (MNA) or 4(4'-nitrophenylazo) phenylamine (DO3) was studied. The photocrosslinkable polymer system, polyvinylcinnamate (PVCN) doped with 3- cinnamoyloxy-4-4-(N, N-diethylamino)-2-cinnamoyloxy phenyl azo nitrobenzene (CNNB-R) was also investigated. Doped NLO active molecules were aligned using the corona poling technique. Infrared spectra as a function of time were used to monitor the relaxation behavior of the oriented dyes after poling. Relaxation of NLO molecules was followed at various characteristic vibrational frequencies. The relaxation of MNA was found to be faster than that of DO3. The NLO dye molecule, CNNB-R was covalently bonded to the host polymer and formed a three dimensional crosslinked network after ultraviolet (UV) irradiation. Relaxation of NLO molecules in pristine and UV treated samples were compared. UV light induced crosslinking provided better temporal stability of molecular alignment in this system ...

Book Synopsis Electronic Processes in Organic Semiconductors by : Anna Köhler
Download or read book Electronic Processes in Organic Semiconductors written by Anna Köhler and published by John Wiley & Sons. This book was released on 2015-06-08 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first advanced textbook to provide a useful introduction in a brief, coherent and comprehensive way, with a focus on the fundamentals. After having read this book, students will be prepared to understand any of the many multi-authored books available in this field that discuss a particular aspect in more detail, and should also benefit from any of the textbooks in photochemistry or spectroscopy that concentrate on a particular mechanism. Based on a successful and well-proven lecture course given by one of the authors for many years, the book is clearly structured into four sections: electronic structure of organic semiconductors, charged and excited states in organic semiconductors, electronic and optical properties of organic semiconductors, and fundamentals of organic semiconductor devices.
