摘要
用循环伏安法研究了中位—四(邻-硝基苯基)四苯并卟啉合锡(IV)氯化物[简记为Sn(IV)TP(o-NO2)TBPCl2]的电化学性质,测得其氧化还原半波电位为:环氧化电位≥0.58V,第一环还原电位-1.33V,第二环氧化还原电位-0.90V.第一环还原标准电子转移速率常数k0为0.357cm/sec.,第二环还原标准电子转移速率常数k0为1.096cm/sec.,并用光谱电化学方法研究了Sn(IV)TP(o-NO2)TBPCl2的氧化还原特性.
With cyclic voltammetry we studied electrochemical properties of meso-tetrakis (o-nitrophenyl)tetrabenzoporphyrin with Sn(IV). The redox half wave potential are:≥0.58 V for oxidation potential of the ring; -1.33 V for the first reduction potential of the ring; -0.90 V for the second reduction potential of the ring. The normal rate constants are:(0.357cm/sec) for the first reduction of the ring; 1.096cm/sec for the second reduction of the ring. We also studied the redox properties of Sn(IV)TP(o-NO_2)TBPCl_2 by spectroelectrochemistry.
