卟啉-金属氧簇超分子化合物的光谱及电催化氧还原
摘要:
应用紫外可见吸收光谱研究了meso四(4N苄基吡啶基)卟啉(MTBPyP4＋,M=H2,Zn)阳离子与金属氧簇阴离子(SiW12O4－40)在水溶液中的光谱行为. 光谱演变及Job图表明MTBPyP4＋与SiW12O4－40在水溶液中可形成稳定的1∶1的超分子化合物. 同时本文还考察了化学计量为1∶1的[CoTBPyP][SiW12O40]超分子化合物的电催化分子氧还原行为, 表明该类超分子化合物有望成为一类新的催化氧还原的修饰电极材料.

Spectra and Electrocatalytic Reduction of Dioxygen of Mesotetrakis (4Nbenzylpyridyl)porphyrinmetaloxo Cluster Supramolecular Complex
Abstract:
Spectral behavior of mesotetrakis(4Nbenzylpyridyl)porphyrinmetaloxo cluster (SiW12O4－40) supramolecular systems in aqueous solution was studied by UVvisible spectrometry.The spectral evolution and Job's plots reveal that the stable aggregates contain equal numbers of the cationic porphyrins and the anionic SiW12O4－40.The electrocatalytic behavior of reducing O2 for the 1∶1 supramolecular complex [CoTMPyP][SiW12O40],was also investigated,the supramolecular complex might be hopeful for being used as a new material of modified electrodes for electrocatalytic reduction of O2.
