双卟啉及其钴络合物的合成

双卟啉及其钴络合物的合成 THE SYNTHESIS OF TWO KINDS OF BIS-PORPHYRIN COMPOUND AND THEIR COBALT COMPLEXES 郑穹 Zheng Qiong and Wu Xuanjie first-author 吴萱阶 本文报导两种双吓啉化合物的合成:用1,3-二溴丙烷联结单羟基四苯基吓啉[Ⅰ]得到双吓啉[Ⅳ],用间苯二酚联结吓啉[Ⅰ],得到双吓啉[Ⅴ],其溶解性较好。分别用DMF或丙酸为溶剂,制备了这两种双吓啉的双钴络合物。这些络合物在旋转盘-环电极实验中显示了对氧的电化还原反应较高的催化活性。 The study of bis-porphyrin compounds is very important. It has been reported that a kind of "face-to-face" dicobalt porphyrin dimers showed highly catalytic activity towards electrochemical reduction of oxygen to water. This paper reports the synthesis of two kinds of bis-porphyrin compound. Linking a couple of monohydroxyl substituted tetraphenylporphine[Ⅰ] by 1,3-dibromopropane gave bis-porphyrin[Ⅳ]. Linking a couple of porphyrin compound [Ⅲ] by resorcinol gave bis-porphyrin [Ⅴ] whichsolubility is better. Using DMF or propionic acid as reaction solvent respeetively, we were able to prepare these bis-porphyrin’s dicobalt complexes. These cobalt complexes showed higher catalytie activity in rotating ring-disk experiment than the common rnetal-porphyrin catalyst Co-TPP. 1985-03-01 2021-04-01 3
