摘要: 本文研究了不对称五氮齿镉和铟大环配合物的激发态性能及其光稳定性。结果表明:它们的三重态能量在120kJ/mol左右,最低激发三重态敏化产生单重态氧的量子产率在0.6~0.9,它们的分子一阶超极化率在~10-28esu,在光照的条件下,配合物Ⅰ相当稳定,而配合Ⅱ则形成不稳定化合物导致光褪色。

Abstract: The properties of the excitedstate asymmetric pentaazadentate macrocyclic Cadmium and Indium complexes and the stability under the visible light are studied. The results show that the energies of the lowest excited triplet state of them are about 120 kJ/mol, the quantum yields of them for generating singlet oxygen are in the range of 0.6-0.9, the first-order molecular hypersusceptibility are about 10-28 esu. Under the visible light, complex is stable, while complex has a less stability.

Key words: pentaazadentate metal complex, excited triplet state, the first-order hypersusceptibility, photobleaching
