Abstract
The p-aminostyrene-N-vinylpyrrolidone copolymer-supported tris(2,2′-bipyridine)ruthenium(II) analogue, [Ru(bpy)2(pbyCOOH)]2+ (bpy=2,2′-bipyridine and pbyCOOH=polymeric bipyridine ligand), has been prepared, and the luminescence behavior of the polymer complex has been investigated in an aqueous solution. The efficiency of the quenching of the excited state of the polymer complex with [Fe(CN)6]4−, [Co(phen)3]2+, and Cu2+ is compared with that of [Ru(bpy)3]2+. The quenching of the excited state of the polymer complex by Cu2+ is strongly enhanced by the effect of the polymer chains. In the polymer complex/Cu2+ system, the quenching by Cu2+ in the presence of poly(p-styrenesulfonate) is much more effective than in the absence of the polyion. The characteristics of the polymer complex in terms of the luminescence behavior are discussed.Keywords
