利用磺酰氯键将苯并15-冠-5和5-(2-羟基苯基)-10,15,20-三(4-硝基苯基)交联,合成了单臂冠醚—卟啉配体(CNTPP)及其金属配合物(CNTPPMn和CNTPPCo)。通过红外光谱、紫外吸收光谱与光电子能谱对化合物和配合物进行结构分析表明,在489cm-1和480cm-1出现M-N键的吸收峰,在1360cm-1和1363cm-1处有S=O键吸收峰。配位中心离子进入卟啉环后引起配合物CNTPPM分子的对称性提高,使Sorct带发生位移,且N原子与金属离子形成配位键后,其中一对N电子结合能升高,另外一对N原子下降,且导致配合物中M2p3/2的电子结合能变大。
By using sulfonyl chloride bond to crosslink benzo 15-crown-5 and 5- (2-hydroxyphenyl) -10,15,20-tris (4-nitrophenyl) Ligand (CNTPP) and its metal complexes (CNTPPMn and CNTPPCo). Structural analysis of the compounds and their complexes by IR, UV and photoelectron spectroscopy showed that the absorption peak of MN at 489cm-1 and 480cm-1 showed the S = O bonds at 1360cm-1 and 1363cm-1 Absorption peak. After the coordination center ions enter the porphyrin ring, the symmetry of the complex CNTPPM molecule is increased, and the Sorct band is displaced. After a coordination bond between the N atom and the metal ion is formed, the binding energy of one pair of N electrons rises and the other pair The N atom decreases and leads to an increase in the electron binding energy of M2p3 / 2 in the complex.
