中文摘要：
树枝形聚合物是一类围绕着中心核,外围链段和官能团呈指数增长的支化高分子.合成方法的发展使发色团可被精确地置于树枝形聚合物的核心、外围甚至支化节点处.树枝形聚合物的特殊结构使其作为模拟光捕获体系被广泛研究.光诱导电子转移和能量传递是光合作用中的重要过程,研究树枝形聚合物体系中的电子转移和能量传递对未来树枝形聚合物在光电器件中的应用有着重要意义.本文综述了近年来光捕获树枝形聚合物体系的研究进展,并重点介绍光捕获树枝形聚合物体系中的能量传递和电子转移过程研究.
英文摘要：
Dendrimers are well-defined tree-like macromolecules having numerous chain ends all emanating from a single core,which makes them an attractive candidate for light-harvesting applications.More importantly,their synthesis is controllable and the accurate positioning of chromophores can be achieved.Photoinduced electron transfer and energy transfer are main processes involved in photosynthesis.Studies on these processes in dendritic systems are important for the future application of dendrimers in optoelectronic devices.In this Focus Review we will discuss recent advances of light-harvesting dendrimers and emphasize the energy transfer and electron transfer characteristics in these systems.
