Abstrakt

Two molecules named QXBT and BXBT with donor-acceptor D-A₂-A₁-A₂-D type of structure were synthesized and characterized by means of electrochemical (Cyclic and Differential Pulse Voltammetry), spectroscopic and spectroelectrochemical (UV–Vis-NIR, Fluorescence and Electron Paramagnetic Resonance) techniques in order to evaluate the impact of different A₂ acceptors on properties of such compounds with benzothiadiazole as A₁ central core and alkylthiophene donor moieties. In the case of QXBT, the quinoxaline and in the BXBT molecule the benzoxadiazole serves as a A₂ unit. The investigations have revealed that changing the A₂ allows to tune the conjugation of molecules and affects not only reduction but oxidation process as well.
