英文摘要：

Dendrimers possess great potentials in molecular devices due to their special chemical structures, which stimulates photochemical and photophyscial investigation of dendrimers. This paper describes the chemical structure characteristics of reported dendrimers with photoinduced intramolecular energy transfer nature in recent two decades,and presents the effects of various factors on photoinduced intramolecular energy transfer efficiency of dendrimers. This review also shows how to tune photoinduced intramolecular energy transfer efficiency based on the properties of energy-donor and acceptor. The application of photoinduced intramolecular energy transfer efficiency in dendrimers is generalized. The key scientific problems in the photoinduced intramolecular energy transfer efficiency in dendrimers are summarized. The development prospects of photoinduced intramolecular energy transfer in dendrimers is discussed.
