Benzothiazole (BTZ)–boron dipyrromethene (BODIPY)-based dyads, Dyad 1 and Dyad 2, containing BTZ as light energy absorbing and transferring antenna while BODIPY as an energy acceptor, linked together with ethoxy and ester spacers, respectively, have been synthesized, and photoinduced energy transfer (PEnT) events occurring within these systems were studied. Both of the dyads were characterized by 1H NMR, MALDI-MS, UV–visible, steady-state fluorescence, and femtosecond transient absorption spectroscopic as well as electrochemical methods. A comparison of the absorption spectra of the dyads with their reference compounds (i.e., BTZ-OMe and BODIPY-OMe) revealed minimal ground-state interactions between chromophores in Dyad 1 while a more pronounced effect in case of Dyad 2. Electrochemical and computational studies revealed that the LUMO of both of the dyads is located on BODIPY, indicating that the reduction of BODIPY moiety is easier as compared to that of BTZ moiety. Selective excitation on BTZ in the dya...
