Current advances in fused tetrathiafulvalene donor–acceptor systems

Abstract

Electron donor (D) and acceptor (A) systems have been studied extensively. Among them, fused D–A systems have attracted much attention during the past decades. Herein, we will present the evolution of tetrathiafulvalene (TTF) fused D–A systems and their potential applications in areas such as solar cells, OFETs, molecular wires and optoelectronics just to name a few. The synthesis and electrochemical, photophysical and intrinsic properties of fused D–A systems will be described as well.
