Superconductive Organic Polymers: Conceptual Design, Synthesis, and Characterization.

Abstract

Here are significant findings of the project for period September 92-96. Theoretical studies indicate that extended chains consisting of isomeric TTF structures have electronic properties and stabilities comparable to TTF extended structures and are therefore of considerable interest as possible polymeric organic superconductive compositions. Synthetic strategies were developed to prepare polymeric TTF and isomeric TTF structures. Dramatically simplified synthetic procedures were developed to prepare TTF and ET-TTF donors in high yield and large quantities from inexpensive starting materials. Developed new techniques to purify, characterize and grow large single crystals of TTF and ET-TTF. Synthesized new organic conductive polymers with good electrical conductivities and processibility. Developed new processing and doping techniques for polyalkylthiophenes to provide consistently high conductivity materials.
