多发色团染料分子内能量传递研究进展

Progress on the Intramolecular Energy Transfer in Multi-chromophoric Dyes

本文综述近几年多发色团染料分子内能量传递领域的研究概况 ,重点介绍了分子内能量传递对组装型多发色团有机染料光稳定性影响的研究进展。设计、合成一个发色团可充当内部光稳定剂的多发色团染料是提高染料光稳定性的一条有效途径。

Intramolecular excitation energy transfer between isolated chromophores on the same molecule in recent years has been reviewed. Many multi chromophoric organic dyes with covalent linkage between the chromophores, one of which can act as a triplet acceptor of the excess energy, have been synthesized and studied. The significant increases in photostability of such assembled dyes have been reported. This is effective way to design new dyes with higher photo stability due that some chromophores can act as internal photostabilizers.
