Syntheses and properties of fused-tetrathiafluvalene oligomers containing dialkoxythiophene units

Abstract

Tetrathiafulvalene oligomers are expected as one-dimensional electronic conductivity to chain direction and are interested as prototypes of moleculer nanowire. In order to improve solubility for the common solvents, we have prepared liner and cyclic oligomers with dialkoxythiophene insereted, and investigated their properties. The donor molecules prepared are expected to realize three-dimensional molecular arrangement baised on side-by-side and pi-pi interactions. In this study, we describe their synthesis and electrochemical properties.
