| 摘 要： | 近年来,含有22个共轭电子的五氮齿大环金属配合物的新物种不断被合成1~2],这类配合物的0-0跃迁吸收带已扩展至大于700 nm的近红外区,作为第二代光动力光疗试剂倍受人们的重视,已在细胞水平上及动物实体瘤的实验中获得肯定结果3~4].最近,又发现这类分子还具有多种非线性光学效应,诸如反饱和吸收和非线性折射等5],可开发成激光限辐材料和器件,在激光防护方面有重要的应用价值.本文合成的不对称五氮齿镉和铟配合物就是这样一类新型化合物,本文报导其合成方法和基本光物理性质.

| Abstract: | In this paper, two new asymmetric pentaazadentate macrocyclic cadmium and indium complexes are synthesized and their electronic spectral properties including the molar extin ction coefficent(ε), the lifetimes of the first singlet excited state, the fluorescence quantum yield are measured. the experiments appear that these complexes exhibit an expanded optical window between the soret and the Q band in visible region and an H aggregation occurred in strong polar solvents. |
