| 摘要: 设计合成了一种新型的不对称卟啉(5，10，15-三苯基-20-{4-[6′-(4″-o-亚水杨基)-苯亚胺基]己氧基}苯基卟啉)及其锌配合物，并用1H NMR、质谱及紫外-可见光谱进行表征。采用紫外-可见光谱滴定法，对锌卟啉与4种咪唑类小分子间的轴向配位反应热力学性质的研究表明：反应为放热、熵增加过程，4种咪唑类配体对锌卟啉的配位平衡常数按KΘ(2-MeIm)>KΘ(N-MeIm)>KΘ(2-Et-4-MeIm)>KΘ(Im)顺序依次减小。运用Z-扫描技术研究了新型卟啉及其锌配合物的非线性光学性质。 |

| Abstract: One novel asymmetry porphyrin (5,10,15-triphenyl-20-{4-[6′-(4″-o-salicylidene)-phenylammonio]hexanoxo}phenylporphyrin) and its zinc complex were synthesized and characterized by 1H NMR, MS and UV-Vis. By means of spectrophotometer technique, the thermodynamic properties of the coordination reaction of zinc porphyrin with four substituted imidazoles were investigated. The reaction is an exothermic process with increase in entropy. For substituted imidazoles, the standard equilibrium constants decrease in the order of KΘ(2-MeIm)>KΘ(N-MeIm)KΘ(2-Et-4-MeIm)>KΘ(Im). The nonlinear optical property of porphyrin and its zinc complexes were studied by Z-scan experiment. |
