文摘

Introduction of electroaccepting groups at the periphery of triphenylamine-based derivatives leads to aninternal charge-transfer band. Syntheses and spectroscopic, electrochemical, and theoretical studies ofvarious 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 finelytuned.
