Photoelectron Spectroscopy of Low-Dimensional Organic Systems
ABSTRACT In the context of electronic devices based on so-called conjugated polymers, it is of critical importance to understand the
effects of exposing the polymers to the conditions encountered during manufacture or the operation of the devices. It has
been shown that photoelectron spectroscopy, in combination with quantum mechanical calculations, is well suited for characterisation
of conjugated polymers, which in many cases behave as nearly one-dimensional systems. Applications of the combined experimental
and theoretical approach are described, to illustrate the nature and the degree of information, which may be obtained. The
approach is applied to studies of the chemical and electronic structure of the pristine polymer materials, as well as studies
of chemical interactions and reactions. Examples discussed include the interaction of water molecules with a particular conjugated
polymer, and chemical reactions which occur upon exposure to UV-light in the atmosphere. Moreover, discussions of the interaction
of metal atoms with the surfaces of conjugated polymers, and nature of the fundamental charge storage states in conjugated
polymers, are included.

ABSTRACT: The authors illustrate the basic physics and materials science of conjugated polymers and their interfaces, particularly, but not exclusively, as they are applied to polymer-based light emitting diodes. The approach is to describe the basic physical and associated chemical principles that apply to these materials, which in many instances are different from those that apply to their inorganic counterparts. The main aim of the authors is to highlight specific issues and properties of polymer surfaces and interfaces that are relevant in the context of the emerging field of polymer-based electronics in general, and polymer-based light emitting diodes in particular. Both theoretical and experimental methods used in the study of these systems are discussed. This book will be of interest to graduate students and research workers in departments of physics, chemistry, electrical engineering and materials sciences studying polymer surfaces and interfaces and their application in polymer-based electronics.Conjugated Polymer Surfaces and Interfaces, by W.
