Abstract
Multifunctional chromophores are synthesized based on dithienothiophene, DDT (π-center) linked through conjugation by donor/donor (D/D) or D/acceptor (D/A) pair segments at the molecular end. Novel electronic/photonic properties are assessed by cyclic voltammetry (CV) and two-photon absorption (TPA). CV shows that the D/D system displays two oxidation/one reduction waves, while the D/A system shows two oxidation/two reduction waves. Such unusual redox is reflected in the amphotericity particularly with D/D system and can be accounted for solely by the involvement of DTT. Exceptionally large TPA cross-section values of these chromophores relative to those based on benzenoid π-center seem to be the result of unique electronic modulation effect of DTT.
