Synthesis and Ultrafast Intramolecular Energy Transfer in BODIPY/Porphyrin-BOPHY Dyads
We report the synthesis and characterization of BOPHY-BODIPY (<b>3</b>) and BOPHY-porphyrin (<b>6</b> and <b>7</b>) dyads, where the BOPHY unit(s) is covalently linked to the <i>meso</i> position of BODIPY or porphyrin. Excited state dynamics of <b>3</b> using pump-probe spectroscopy revealed a 345 fs energy transfer from BOPHY to BODIPY and a 14 ps electron transfer from BODIPY to BOPHY. BOPHY-porphyrin dyads (<b>6</b> and <b>7</b>) displayed 90-100 fs energy transfer from BOPHY to porphyrin, but no electron transfer was observed.
