摘要: Abstract π-Conjugated polymers consisting of 1,10-phenanthroline units and crown ether subunits (Poly-1, Poly-2, Poly-3) were prepared by dehalogenation polycondensation the corresponding dibromo monomers using a zero-valent nickel complex as condensing agent. They characterized elemental analysis, 1H NMR UV–Vis spectroscopies, cyclic voltammetry (CV). partly soluble in CHCl3, number average molecular weight part which had 15-crown-5 subunits, was estimated to be 5300. The exhibited peaks at approximately λmax = 360 nm, reasonable. Complexation with [Ru(bpy)2]2+ alkaline metal ions made polymer organic solvents. complexation unit proceeded quantitatively, complexes CV curves characteristic [Ru(N-N)3]2+ complexes.
