Porphyrin‐Ryleneimide Hybrids: Low‐Bandgap Acceptors in Energy‐Transfer Cassettes

Efficient energy and electron transfer in photoexcited dye assemblies is of fundamental importance in both biological and artificial light-harvesting systems. Efficient transfer according to the Förster mechanism is now reported in multi-chromophore cassettes consisting of four BODIPY units rigidly linked to a pseudo-tetrahedral acceptor dye. This central chromophore was obtained by fusing porphyrin and perylenediimide motifs and displays strong absorption extending into the near infrared.
