摘要
合成了一组不同碳链的胆甾醇酯侧链卟啉配体和金属Zn配合物.研究了它们的吸收光谱和发射光谱.将这些卟啉配体以一定浓度掺杂在聚甲基丙烯酸甲酯(PMMA)中制成固体薄膜,发现由于在卟啉环上引入了手性的胆甾醇酯侧链,卟啉化合物在soret带和Q带均有较强的CD吸收,这种现象可能是卟啉环上的四个手性胆甾醇酯侧链与四苯基卟啉环发生偶合作用.进一步还发现这些卟啉化合物的圆偏振吸收性质与在PMMA中的浓度有关.
A series of porphyrin compounds and Zn complexes with cholesterol ester side chains were synthesized and their UV-Vis and fluorescence spectrum were tested. CD spectrum showed that these compounds in polymethyl methacrylate （PMMA） solid film had circular dichroism property in soret and Q bands because of mutual coupling between chiral cholesterol ester moieties and tetraphenylporphyrin ring, furthermore, it was found that the CD spectrum of cholesterol ester porphyrin compounds was changed along with concentration of these compounds in PMMA solid film.
