摘要：

The design principles for a light harvesting system that may spontaneously evolve toward greater efficiency for energy transfer are discussed and a new system based on these principles is introduced. The system consists of a tetraphenylchlorin as the antenna and a phthalocyanine as the energy acceptor in a poly(vinylpyridine) matrix. Excitation of the antenna leads to strong emission from the acceptor. Long term illumination of the film leads to increasing quantum efficiency for the energy transfer process. Some possible mechanisms for this evolution are discussed as are some possible improvements of the system.
