Abstract
Four BODIPY dyes (6a ~ 6d) with electron-donating or electron-withdrawing groups at the meso-position were synthesized by Sonogashira coupling reaction of thieno[3,2-b]thiophene with mono-iodo-BODIPY moiety. All compounds were fully characterized by 1H NMR and MALDI-TOF MS. Their photophysical and electrochemical properties were studied by UV-visible absorption spectroscopy, steady-state and time-resolved fluorescence spectroscopy, two-photon excitation spectroscopy and cyclic voltammetry. These conjugated dyes exhibit interesting photophysical properties such as high molar extinction coefficient, large Stokes shift and high two-photon absorption cross section σ2.
