Synthesis of ternary BODIPY-(Zn-porphyrin) 2 conjugates aimed at the structure-specific photoresponse

This work aims to design BODIPY-(Zn-porphyrin) 2 conjugates that channel all harvested light energy into one conjugate moiety, providing a specific photoresponse with an extended excitation range. Three BODIPY-porphyrin conjugates have been prepared, and their excitation energy deactivation channels have been established. In two of them, the BODIPY π-conjugation was extended at either the 2,6-positions or the 3,5-positions via Sonogashira coupling. Then the click reaction was applied to conjugat
