This book is based on a research study in synthesis and characterization, properties and investigation of new monomers and polymers containing electroactive fragments. Some of the derivatives could be used as hole transporting materials as well as hosts in organic light emitting diodes or in electrographic photoreceptors. Also there are presented series of new crosslinkable derivatives their synthesis, characterizaton, preparation and investigation for electroactive polymeric networks. Some of the insoluble electroactive systems are suitable for preparation of multilayer organic light emitting devices.

The book focuses on the development of high performance, high efficiency electroactive polymers (EAPs), and electromechanically active polymers by controlling molecular chemical structure and morphology for all applications. This book is ideal for academicians and researchers in polymer and materials science.

Since the first redox-flow batteries (RFBs) were demonstrated in the 1940s, RFBs attracted attentions duet to their relatively high specific capacity, excellent cycle life and flexible layout. Traditional RFBs were constructed by using inorganic redox materials such as Vanadium salt. The cost of those systems is usually expansive and the materials are toxic. The conjugated molecules represented another class of redox materials that can be produced with abundant nature sources and provide better capacity/cost ratio. However, the most challenge to achieve the desired organic redox-flow batteries (ORFBs) is to design and synthesize ideal organic redox molecules with high solubility, large electrochemical window and reversible redox cycles. In this research, we focused on exploring electro-active conjugated molecules with high solubility and redox stability in non-aqueous condition. Diketopyrrolopyrrole (DPP), phenanthridinone (PN), ferrocene and viologen based molecules were designed and synthesized, and their electrochemical characteristics were studied.

Electroactive materials are playing an ever increasing role in science and technology. At present the wide range of applications for these materials include electrodes and membranes for electrochemical energy conversion and storage, electroceramic devices and sensors, organic diodes, magnetic and optical devices, and photoresists. The book summarizes the results of the special research program ‘Electroactive Materials’ established by the Austrian Science Fund. Contributions deal with plastic solar cells (invited review); conjugated polymers and organosilanes; thin-film zinc/manganese dioxide electrodes; the anode/electrolyte interface in lithium ion batteries; a novel technique for manufacturing highly conductive composite materials; a new method for conductivity relaxation measurements on mixed conductors; the application of surface science to thin films and interfaces of electroactive organic materials; preparation and radical oligomerisation of an Fe(II) complex without loss of spin-crossover properties; phase gratings in photoreactive polymers as a way to optically pumped organic lasers; and high-spatial resolution elemental analysis and mapping by analytical electron microscopy.
