Molecular Engineering of the Internal Charge Transfer in Thiophene−Triphenylamine Hybrid π-Conjugated Systems

Introduction of electroaccepting groups at the periphery of triphenylamine-based derivatives leads to an internal charge-transfer band. Syntheses and spectroscopic, electrochemical, and theoretical studies of various derivatives which differ by the strength and the number of electroacceptor groups are presented. These various results show that the ICT band and the acceptor/donor abilities of derivatives can be finely tuned
