电化学方法构筑直结型卟啉高分子

Construction of meso - Linked Porphyrin Polymers via Electrochemical Oxidative Coupling

利用电化学方法成功地合成了不含其它连接基团的卟啉高分子,循环伏安图谱中发现该高分子在电极上的沉积为紧密型沉积,所得产物的紫外-可见吸收光谱表明相邻的卟啉环在该高分子链中均成平面直角结构,FT-IR图谱表明卟啉环之间是通过C—C键在meso位上相连,质谱图证明该高分子的链长可以达到13个卟啉环以上.

5,15- bis - (3,5-di- tert - butylphenyl) porphyrin zinc and copper complexes were polymerized through electrochemical oxidation. The absorption spectra of the resultant polymers exhibit exciton coupling band in either solid state or solution. FT - IR spectra confirm that the porphyrin rings are connected to each other via a single C-C bond at the meso position. Mass spectra clearly show that the repeat units of porphyrin ring in the polymeric chain of poly - ZnBBPP are more than 13.
