Structure–reactivity relationships in bithiophenic precursors based on the 3-phenoxythiophene building block

Abstract

3-Toluoxythiophene and bithiophenes diversely substituted by toluoxy groups have been synthesized. Theoretical, spectroscopic and electrochemical studies show that the number and position of the phenoxy groups exert a strong influence on the geometry of the ground state and cation radical and determine the reactivity of the latter and hence its aptitude for electropolymerization.
