Anthradithiophene derivatives substituted at the 2,8-positions by formyl and triphenylamine units: Synthesis, optical, and electrochemical properties

Abstract

The synthesis and characterization of two new anthradithiophene (ADT) derivatives substituted by thiophenyl or 2-octylthiophenyl units at the 5,11-positions and donor (triphenylamine) or acceptor (aldehyde functions) moieties at the 2,8-positions of their backbone are described. Optical measurements were performed to evaluate the effect of electron-rich/-poor substituents on their stability towards photo-oxidation and were supported by quantum chemical calculations and cyclic voltammetry experiments.
