用中－四（对二甲基丙磺基胺基）苯基卟啉作光敏剂，在电子给体三乙醇胺（ＴＥＯＡ）和电子受体甲基紫精（ＭＶＩ＿２）存在的情况下，研究了ＴＥＯＡ／ＭｅＴＰＳ／ＭＶ￣（２＋）／ＤＭＳＯ＋Ｈ＿２Ｏ（Ｖ／Ｖ＝８０：２０）体系的光敏化还原ＭＶ￣（２＋）动力学，并由动力学参数ａ，光诱导时间ｔ＿ｉ，初始反应速率υ＿０来衡量光敏剂的优劣。
In the presence of electron donor triethanolamine (TEOA) and electron acceptor methyl viologen (MVI_2), a novel photosensitizer was synthesized by using tetrakis (p-dimethylpropanesulfonylamino) phenylporphyrin The kinetics of photosensitized reduction was investigated by kinetic parameters a, photoinduced time t_i and initial reaction rate υ_0, using TEOA / MeTPS / MV¯ (2 +) / DMSO + H_2O solution with V / V = 80:20 Measure the pros and cons of photosensitizers.
