Synthesis of Tetrabenzoporphyrins Fused with Fluoranthenes
摘要:
Tetrabenzoporphyrins fused with fluoranthenes were prepared by the retro Diels-Alder reaction of the precursors composed of a porphyrin and four fluoranthenes connected with bicyclo[2.2.2]octadiene (BCOD). These porphyrins exhibited the Soret (480-494 nm, epsilon = 243,000-277,000) and intense Q bands (739-760 nm, epsilon = 375,000-509,000). Free bases and Zn complexes of them fluoresce at 760 nm and 746 nm with small Storks shifts and high quantum yields of 30 and 10 %, respectively.
