Book Description

The goal of this research is to study the excited state dynamics of conjugated molecules, oligomers and polymers in the solid state and compare these photophysical properties to those found in solution. To study the triplet excited state dynamics of films a new nanosecond transient absorption instrumentation was developed. This instrument can detect transient absorption with ... A as low as of 10-3. Using this newly available instrumentation, it is possible to measure the triplet excited state dynamics so as to gain insight into several solid-state applications of photoactive molecules, oligomers, and polymers. A series of p-phenylene vinylene platinum acetylide complexes are studied for optical power limiting applications, and they are incorporated into poly(methyl methacrylate) (PMMA) monoliths. The photophysical properties of the monoliths and Triplet-triplet annihilation in conjugated co-polymers containing phenylene and p-phenylene vinylene platinum acetylide units is observed and compared against representative "monomer" complexes using transient absorption spectroscopy as a function of increasing laser fluence of the excitation pulse. The interaction between conjugated polymer, MEH-PPV, and a trimeric perfluoro-ortho-phenylene mercury complex, Hg3 is investigated in solution and in films. Finally cationic oligomers are intercalated into a clay host, and the photophysical properties of the clay-oligomer hybrid are investigated in disperse solutions and in films.

Book Description

Although, carbon is only one of one hundred plus elements, the polymer science lit erature consists primarily of studies on carbon based polymers. In part, this reflects the varied feedstock sources and in part, the type of bonds and bond forming reactions avail able to form organic polymers that are not available to the inorganic and organometallic chemist. However, recent intense interest in polymers with novel optical, electronic or magnetic properties or polymers that can serve as precursors to ceramic, semiconductor, metallic or superconductor materials has served as a driver for the development of novel synthetic routes and characterization techniques that have launched many new inorganic and organometallic oligomers and polymer systems. The following chapters represent an effort to provide an overview of several new and continuing areas of development in inorganic and organometallic polymer science. This book represents the second in a series of books we have edited on inorganic and organometallic polymer chemistry (1. Transformation of Organo-metallics into Common and Exotic Materials, NATO ASI Series Vol 141. 3. Inorganic and Organometallic Polymers with Special Properties, NATO ASI Series in press). In this series, we attempt to develop, for the reader, an understanding of the breadth, depth and potential of inorganic and organometallic polymer science.

Book Description

Reactive oligomers (ROs) constitute a starting material for the production of numerous polymeric materials with a pre-assigned set of physico-mechanical and physico-chemical properties. This book is the first to treat systematically various methods for determining the FTD and MWD of functional oligomers. Special attention is given to the application of liquid chromatography in different separation modes: exclusion (gel-permeation chromatography, GPC) and adsorption, as well as to the separation of functional oligomers in the critical region (SCR) at the boundary between the specified modes.

Book Description

The book gives an original interpretation of modern ideas about oligomers as substances which, due to their molecular structure, exhibit peculiarities of statistical behaviour different form the statistics of monomers and polymers. The criteria are given that enable one to distinguish between the ranges of monomers, oligomers and polymers in homologous series. Theoretical aspects of a small-scale oligomer structure of and models for the formation of the supermolecular and the organization of liquid oligomeric systems are presented. The theoretical and experimental results of studying phase transitions and anomalies of physicochemical properties inherent to oligomeric systems are considered.

Book Description

Metal- and metalloid-containing macromolecules are defined as large molecules (i.e., polymers, DNA, proteins) that contain a metal or metalloid group affiliated with the molecule. This volume describes what is possible with metal-containing polymers where the metal is an essential ingredient in obtaining desired optical and electronic properties. Covering applications in nonlinear optical materials, solar cells, light-emitting diodes, photovoltaic cells, field-effect transistors, chemosensing devices, and biosensing devices, this indispensible guide focuses on the photochemistry and photophysics of metal-containing polymers, with chapters by leading contributors to the core advances in this field.
