Abstract:
Cerium (III) tetraphenylporphyrin nitrate Ce(TPP)NO3 was synthesized by using meso-tetraphenylporphyrin (TPP) and Ce(NO3)·6H2O in mixture solution of CHCl3 and C2H5OH (V :V =1:1). The complex was characterized by UV-Vis, FT-IR, conventional uorescence, MALDI-TOF-MS, and 1H NMR spectral techniques. The structure of complex was pro-posed viaSpectral analyses, in which tetraphenylporphyrin was coordinated to a cerium ion in a tetradentate fashion, while one nitrate was coordinated to the same cerium ion. Af-ter bubbling NO to the solution of Ce(TPP)NO3 in CH2Cl2, spectral analyses suggested that Ce(TPP)NO3 could interact with NO to form a novel complex of Ce(TPP)(NO)NO3, and NO was coordinated to the center cerium ion. When nitrogen was poured into the Ce(TPP)(NO)(NO3) solution, the complex could be reduced to Ce(TPP)NO3.

摘要:
在氯仿与无水乙醇的混合溶剂(体积比为1:1)中,四苯基卟啉(TPP)与Ce(NO3)·6H2O混合反应后,得产物Ce(TPP)NO3. 通过紫外-可见光谱、红外光谱、荧光光谱、质谱、核磁共振氢谱的分析与表征,四苯基卟啉与铈原子以四齿方式进行配位,在同一个铈原子上还有一个硝酸根配位. 向Ce(TPP)NO3的二氯甲烷溶液中通入NO气体,NO可以配位在同一个铈原子上,得到新的配合物Ce(TPP)(NO)NO3,向此溶液中通入N2,金属卟啉配合物可以恢复为配合物Ce(TPP)NO3.
