Book Description
Conjugated polymers have important technological applications, including solar cells and light emitting devices. They are also active components in many important biological processes. In recent years there have been significant advances in our understanding of these systems, owing to both improved experimental measurements and the development of advanced computational techniques. The aim of this book is to describe and explain the electronic and optical properties of conjugated polymers. It focuses on the three key roles of electron-electron interactions, electron-nuclear coupling, and disorder in determining the character of the electronic states, and it relates these properties to experimental observations in real systems. A number of important optical and electronic processes in conjugated polymers are also described. The second edition has a more extended discussion of excitons in conjugated polymers. There is also a new chapter on the static and dynamical localization of excitons.

Book Description
This book sheds new light on the dynamical behaviour of electron spins in molecules containing two unpaired electrons (i.e. a radical pair). The quantum dynamics of these spins are made complicated by the interaction between the electrons and the many nuclear spins of the molecule; they are intractable using analytical techniques, and a naïve numerical diagonalization is not remotely possible using current computational resources. Hence, this book presents a new method for obtaining the exact quantum-mechanical dynamics of radical pairs with a modest number of nuclear spins. Readers will learn how a calculation that would take 13 years using conventional wavepacket propagation can now be done in 1 day, and will also discover a new semiclassical method for approximating the dynamics in the presence of many nuclear spins. The new methods covered in this book are shown to provide significant insights into three topical and diverse areas: charge recombination in molecular wires (which can be used in artificially mimicking photosynthesis), magnetoelectroluminescence in organic light-emitting diodes, and avian magnetoreception (how birds sense the Earth’s magnetic field in order to navigate).

Book Description
A detailed, up-to-date review of transition metal-containing polymers Promising advances in the electrical, optical, magnetic, biological, and catalytic properties that metal-containing polymers possess have led to notable expansion in the field of transition metal-containing polymers. Frontiers in Transition Metal-Containing Polymers provides a comprehensive, up-to-date review of the synthesis, properties, and applications of transition metal-containing polymers, including an overview of the historical development of these types of polymers. Written by the leading researchers in the field, this thorough volume covers the routes to organometallic and coordination polymers, as well as characterization and applications of transition metal-containing monomers and polymers. Other topics discussed include: Metallo-supramolecular coordination polymers based on nitrogen ligands Coordination polymers based on phosphorus ligands Polypeptide-based metallobiopolymers and DNA-based metallopolymers Metallodendrimers Self-assembly of metal-containing block copolymers Applications including drug delivery, optics, molecular devices, sensors, conductive materials, and more

Book Description
Experimental and theoretical studies have shown that excitonic effects play an important role in the optical properties of conjugated polymers. The optical absorption spectrum of trans-polyacetylene, for example, can be understood as completely dominated by the formation of exciton bound states. We review a recently developed first-principles method for computing the excitonic effects and optical spectrum, with no adjustable parameters. This theory is used to study the absorption spectrum of two conjugated polymers: trans-polyacetylene and poly-phenylene-vinylene(PPV).
