水溶性卟啉配合物的合成及光敏化行为

Synthesis,Characterization of Water Soluble Porphyrin and Its Photosensitization Behavior

在低沸点的氯仿溶剂中合成了中－四（对二甲基丙磺酸基氨基）苯基卟啉（简记为Ｈ２ＴＰＳ），在乙酸溶剂中合成了相应的金属卟啉［简记为ＭｅＴＰＳ，Ｍｅ＝Ｚｎ（Ⅱ），Ｃｕ（Ⅱ），Ｎｉ（Ⅱ），Ｃｏ（Ⅲ），Ｍｎ（Ⅱ）］，并进行了表征． ＴＥＯＡ－ＭｅＴＰＳ－ＭＶ２＋－ＤＭＳＯ（Ｈ２Ｏ）（７５：２５，Ｖ／Ｖ）体系的光敏化还原ＭＶ２＋反应的研究结果表明，Ｚｎ（Ⅱ）ＴＰＳ、Ｍｎ（Ⅱ）ＴＰＳ及Ｈ２ＴＰＳ是较好的光敏剂，且以Ｚｎ（Ⅱ）ＴＰＳ为最好。

The title comlexes,meso-tetrakis( 4-dimethylsufonatopropylanilino)metalloporphyrins[abb.,Metps,Me=H2,Zn(Ⅱ),Cu(Ⅱ),Ni(Ⅱ),Mn(Ⅱ/Ⅲ), Co(Ⅲ)]were synthesized in acetic acid solvent and characterized by UV-visble, IR spectra and elemental analyses.The electron transfer bewteen triethanolamine(TEOA) and methylviologen(MV2+) was photosensitized by the metalloporphyrins excited by visible light in DMSO solution contining 25%(V/V) water at room temperature. The results show that Zn(Ⅱ)TPS is the best photosensitizer in all of MeTPS.
