Synthesis of unsymmetrical tetrathiafulvalenes and electrical conductivities of their tetracyanoquinodimethane complexes

Abstract

The preparation of some unsymmetrical tetrathiafulvalenes and the electrical conductivities of their charge transfer complexes with tetracyanoquinodimethane (TCNQ) are described; the ethylenedithio(trimethylene)tetrathiafulvalene–TCNQ complex exhibited higher conductivity than complexes of tetrathiafulvalene, tetramethyltetrathia-fulvalene, and hexamethylenetetrathiafulvalene with TCNQ.
