Electrogenerated Chemiluminescence. 42. The Electrochemistry and Electrogenerated Chemiluminescence of the Tris(2,2'-bipyrazine)ruthenium(II) System

摘要

The electrochemical behavior and electrogenerated chemiluminescence (ecl) of of Ru(bpz)3(2+) (as the PF6- salt) in acetonitrile solutions was investigated. Oxidation to the +3 form and reduction to the +1, 0, -1 and -2 forms occur at potentials about 0.5V more positive than the corresponding bipyridine complex. Emission characteristic of Rub(bpz)3(2+) is produced upon the electron transfer reaction between the +3 and +1 species. Weak emission also results from reaction of the +3 species with solvent or impurities. (Author)
