Redox Reactions of Peroxo Terpyridine Complexes of Cu(II),Zn(II), and Cu(II)-Zn(II):A Pulse Radiolysis Study

摘要

The reactions of e_(aq)-, CH_2OH~.,(CH_3)_2COH~.,OH~.and N-3~. radicals with peroxo terpyridine complexes of Cu(II),Zn(II), and Cu(II)-Zn(II)in aqueous solution were investigated by pulse radiolysis. The primary products from the reduction and oxidation of the macrocyclic complexes were assigned a radical nature by comparing their optical spectra with those of Cu(I), Zn(I), and Cu(III) species. Such metal-ligand radical products undergo disproportionation that does not lead not lead to the formation of Cu(0)or colloidal copper.
