Impacts of Dibenzo- and Dithieno-fused Structures at the b, g Bonds in the BODIPY Skeleton

Abstract

Abstract Dibenzo[b,g]-fused and dithieno[b,g]-fused BODIPY derivatives were synthesized, and the electronic effects of the introducing dibenzo- and dithieno-fused structures at both of the b and g bonds in the BODIPY skeleton were investigated. Electrochemical and photophysical measurements demonstrated that these structural modifications effectively enhance the electron-accepting ability of the BODIPY skeleton leading to the red-shifted absorption.
