摘要: 本文合成了苯并[15-冠-5]取代的酞菁化合物,研究了铷离子诱导的冠醚酞菁二聚行为的光谱特性,观察到冠醚酞菁形成二聚体的光谱变化分三阶段进行,与铷离子的浓度密切相关,这是由于二聚体中酞菁环从非共平面构象最终转变为面对面的超分子结构的结果;详细介绍了对紫外可见吸收光谱中重叠光谱的数据处理方法,从而计算了二聚体形成的平衡常数K值。

Abstract: A tetrabenzo[15-crown-5] substituted phthalocyanine was synthesized and the spectroscopic behavior of Rb+-induced dimerization of crowned phthalocyanine has been studied. It was found that the cation-induced dimerization proceeds in three stages which depends on the concentration of the ions.The experimental data obtained by UV-VIS absorption studies were analyzed with a computer program and the monomer-dimer equilibrium constant was calculated.

Key words: supramolecule, crown ether substituted phthalocyanine, noncofacial dimer, cofacial dimer
