树枝状聚合物光捕获特性的研究进展

近年来，光捕获的特性除了在自然界同时也在许多树枝状聚合物分子上体现出来，并引起广泛关注。在讨论几种可能存在的能量传递机理前提下，总结了国内外近期对几种不同类型的树枝状聚合物光捕获特性的研究情况。发现不同的树枝状结构，能量转移的机理是不同的。而其中大部分的试验研究结果认为，F6rster机理是主要的。这些研究工作将对我们进一步研究树型分子材料，模拟自然界中的能量传递过程以至发展新型的光子器件有相当大的指导意义。

Recent Progress in Light-Harvesting Dendrimers

Recently, it has been realized that dendrimers can exhibit the light-harvesting properties. New recent developments are discussed. The preparation of dendritic structures and assemblies composed of numerous light-collecting chromophores that transfer their energy to a single energy trap at the core has been achieved in a number of diverse and creative ways. The Foerster mechanism is considered most important in those papers. It can be used to simulate the natural photosynthetic systems collect sunlight. At the same time, these novel structures are being used as many photonic devices.
