Abstract
Broadband capturing and FRET‐based light‐harvesting molecular triads, CRBs, based on the coumarin–rhodamine–BODIPY platform were rationally designed and synthesized. The absorption band of CRBs starts from blue–green to yellow–orange regions (330–610 nm), covering the strong radiation scope of sunlight. The peripheral coumarin and BODIPY chromophore energy could transfer to the central acceptor rhodamine by a one‐step direct way. The energy of the coumarin moiety could also transfer to the BODIPY unit, subsequently transferring to the rhodamine core by two‐step sequential ways. Both the efficiencies of the coumarin moiety and the BODIPY unit to the rhodamine core in CRBs, determined by two different ways, are very high.
