研究了两种单取代羟基四苯基卟啉——— 5 - (4-羟基苯基 ) - 10 ,15 ,2 0 -三苯基卟啉 (H2 POH)和 5 - (4-羟基苯基 ) - 10 ,15 ,2 0 -三氯苯基卟啉 (H2 (p -Cl) 3 POH)在冰醋酸中和吸附于AgCl溶胶表面的电子吸收光谱(UVA)和化学反应 .结果表明 ,在冰醋酸中H2 POH和H2 (p -Cl) 3 POH均以二酸和游离碱的形式存在 ;在乙醇中 ,pH值为 10 .5 - 11.5时 ,H2 POH与H2 (p -Cl) 3 POH在AgCl表面发生配位反应 ,生成了Ag(Ⅱ )POH和Ag(Ⅱ ) (p -Cl) 3 POH ,并且溶液的酸度越低 ,配位反应的速度越大 Two kinds of monosubstituted hydroxytetraphenylporphyrins - 5 - (4 - hydroxyphenyl) - 10,15, 20 - triphenylporphyrin (H2 POH) and 5 - (4 - hydroxyphenyl ) - 10, 15, 2 0 - trichlorophenyl porphyrin (H2 (p -Cl) 3 POH) was neutralized in glacial acetic acid by electron absorption spectroscopy (UVA) and chemical reaction on the surface of AgCl sol.The results showed that Both H2 POH and H2 (p -Cl) 3 POH in glacial acetic acid were present as diacid and free base. In ethanol, H2 POH and H2 (p -Cl) 3 POH Coordination reaction occurs on the surface of AgCl to form Ag (Ⅱ) POH and Ag (Ⅱ) (p -Cl) 3 POH, and the lower the acidity of the solution, the faster the coordination reaction
