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—mv ̄2+发生了分子内从卟啉到甲基紫精的电子迁移反应.在ZnTCMPP-mv ̄2+/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.
In this paper, tetrakis (p-chloromethyl) phenyl-methyl viologen porphyrin and its complexes of Zn, Co and Mn were synthesized and characterized by elemental analysis, IR and UV-Vis spectra. Their photochemical properties were studied. The results show. The photolysis in TEOA caused the intramolecular electron transfer reaction of MTPMPP-mv2 + from porphyrin to methyl viologen. Photochemical reduction of mv2 + can occur in ZnTCMPP-mv ~ 2 + / TEOA / DMSO-H2O system, resulting in a more stable mv +. In the Mn (Ⅲ) TCMPP-mv2 + / CH3OH / H2O system, the photooxidation of methanol can occur and the formaldehyde of the oxidation product is detected.
