A series of dendritic systems, which are capable of funneling energy from the periphery to the core, have been synthesized. The photophysical properties of the dendrimers, generations 0-2, have been determined. The light-harvesting ability of these compounds increases with increasing generation arising from the increase in molar extinction coefficient. Selective excitation of the donor leads to an efficient energy transfer (>90 %) to the acceptor. The approach provides a facile synthesis for modification of near-infrared BF2-Azadipyrromethene.
已经合成了一系列能够将能量从外围引导至核心的树枝状体系。已测定了第0 - 2代树枝状大分子的光物理性质。这些化合物的光捕获能力随着代数的增加而增强，这是由于摩尔消光系数的增加所致。供体的选择性激发导致向受体的高效能量转移（>90%）。该方法为近红外BF2 - 氮杂二吡咯亚甲基的修饰提供了一种简便的合成方法。
