在可见光照射下,水溶性的四苯基磺酸锌卟啉(ZnTPPS),当有还原剂存在时,可使连吡啶双盐如甲基紫精MV~(2+)还原成一价甲基紫精MV_·~+。在铂催化剂存在下,MV_·~+又可将H_2O还原成H_2。由于H_2是一个重要能源,此反应近年来深受重视。 4,4′-连吡啶双盐与ZnTPPS的相互作用已有报导,但中间夹一个苯基的双吡 In the visible light irradiation, water-soluble zinc tetraphenyl sulfonate (ZnTPPS), in the presence of a reducing agent, can make double pyridine salt such as methyl viologen MV ~ (2+) reduced to monovalent methyl violet Fine MV_ · ~ +. In the presence of platinum catalyst, MV_ · ~ + can reduce H_2O to H_2. Since H 2 is an important energy source, this reaction has drawn great attention in recent years. The interaction of 4,4’-dipyridyl bis-salt with ZnTPPS has been reported, but the dipyridyl with one phenyl group
