The preparation and characterization of a pendant polymer complex of [Ru(biq)2(pvbpy)] (ClO4)2 are described [biq = 2,2’-biquinoline; = pvbpy = poly(4-methyl-4’-vinyl-2,2’-bipyridine)]. The UV-visible absorption and luminescence properties of the complex are measured. Cyclic voltammetry is used to characterize the complex and to enable preparation of the reduced pendant polymer complex samples. The electron spin resonance data for the reduced one-, two-, three-, and four-electron-reduced species indicate that the reduced species are each S = 1/2 ligand-localized materials. The first- and second-electron-reduction species give ESR signals with temperature-dependent line broadening. The third- and fourth-electron-reduced species show ESR signals without temperature-dependent line broadening but produce ESR signals with hyperfine structure.
