| 摘要: 本文合成了四(对-氯代甲基)苯基-甲基紫精卟啉及其Zn、Co、Mn配合物,用元素分析、红外光谱和紫外可见光谱进行了表征。研究了它们的光化学性质。结果表明。在TEOA中光照使M·TCMPP-mv2+发生了分子内从卟啉到甲基紫精的电子迁移反应。在ZnTCMPP-mv2+/TEOA/DMSO-H2O体系中可发生光敏化还原mv2+反应,生成较稳定的mv+.在Mn(Ⅲ)TCMPP-mv2+/CH3OH/H2O体系中可发生光助氧化甲醇反应,并检出了氧化产物甲醛。 |

| Abstract: The covalently linked 5, 10, 15, 20-tetra(p-chloromcthyl) phenyl porphyrinmethylviologen zinc, manganese and cobalt complexes(abb:MTCMPP-mv2+) were synthesizedand characterized by clemental analysis,UV absorphon spectra and IR spectra.Thephotochemical behavior of MTCMPP-mv2+ was steadied.In deaceratcd solution containingtriethanolaminc(TEOA),the intramelocular electron transfer from porphyrin to viofogen takesplace under steady state irradiation.In the deaerated soluhon of MTCMPP-mv2+/TEOA/DMSO-H2O system photosensitized reduchon takes place and reduced methylviologen was formed. In deaerated solution of M(Ⅲ)TCMPP-mv2+/CH3OH/H2O systemphotooxidation reaction of methanol takes place with a product methanal formed. |
