Dendritic molecules due to its unique chemical structure, its photochemical and photophysical research aroused people’s attention. This article focuses on the chemical structure of dendrimers with light-induced intramolecular energy transfer reported in recent two decades and analyzes the influence of different factors on the energy transfer efficiency in light-induced dendrimers. And the nature of the acceptor, the intramolecular light-induced energy transfer of the dendrimers is regulated. The current applications of dendrimers with light-induced intramolecular energy transfer properties are summarized. The intramolecular energy transfer in dendrimers is summarized Key scientific issues and prospects for the development of dendrimers with light-induced intramolecular energy transfer.
