【 摘 要 】

Studies on the luminescence quenching of Ru(phen)$^{2+}_{3}$ (phen = 1,10-phenanthroline) by the polymer-cobalt(III) complex ions, cis-[Co(phen)2(BPEI)Cl]2+ and cis-[Co(bpy)2(BPEI)Cl]2+ (bpy = 2,2'-bipyridine, BPEI = branched polyethyleneimine) in DNA as well as in various micellar media by steadystate emission spectroscopic technique have been reported. The quenching rate constants were arrived through Stern-Volmer equation. The results have been analysed based on hydrophobic as well as electrostatic binding between polymer-cobalt(III) complexes and DNA/micelles.
