| 摘 要： | 报道了一种新型尾式锌卟啉(o-PyOC6H12OTPPZn)的合成及表征, 采用紫外-可见光谱滴定法对该化合物与5种吡啶类小分子间的轴向配位反应的热力学性质进行了研究. 轴配体系的热力学数据显示, 5种吡啶类配体的平衡常数按K(4-MePy)>K(Py)>K(3-MePy)>K(2,4,6-triMePy)>K(2-MePy)依次减小, 吡啶类小分子对主体的配位能力按4-MePy>Py>3-MePy>2,4,6-triMePy>2-MePy依次减弱, 同时分子模拟的理论研究得到了与实验完全一致的结果. 通过Z-扫描实验对该化合物的非线性光学性质的研究表明, 该样品具有较强的反饱和吸收特征.

| Abstract: | A new kind of tailed zinc porphyrin modified by pyridine derivative(o-PyOC6H12OTPPZn) was synthesized and characterized by elementary analysis,UV-Vis,1H NMR,IR,and MS spectra.The axial coordination reaction was studied between o-PyOC6H12OTPPZn and pyridine derivatives by UV-Vis spectra titration.The binding constants decreased in the order of K(4-MePy)>K(Py)>K(3-MePy)>K(2,4,6-triMePy)>K(2-MePy) for pyridine derivatives.The results show that the capability of axial ligands decreased in the sequence of 4-MePy... |
