What is Photo-induced electron transfer and electrocatalytic properties of novel charge-transfer compound (TMB)3HPMo12O40 about?

A novel charge-transfer compound (TMB) 3 PMo 12 O 40 (TMB-PMo 12 , TMB = 3,3 0 ,5,5 0 -tetramethylbenzidine) was synthesized. There is a strong electronic interaction between organic donor TMB and PMo 12 O 3À 40 heteropoly anion. Irradiation of ultraviolet light can cause the intramolecular electron-transfer between TMB and heteropoly anion in the complex. Electrochemical behavior of the TMB-PMo 12 modified electrode in H 2 SO 4 solution showed well-defined redox couples corresponding to the redox reactions of the incorporated TMB and heteropoly anion. The TMB-PMo 12 modified electrode exhibits excellent catalytic activity for the reduction of IO À 3 , where the incorporated TMB may play an important role to activate the catalytic activity of the heteropoly anion.
