摘　　要：NiCl2(bpy) catalyzed polycondensation between p-dibromobenzene and m-dibromobenzene has been carried out under various conditions. The polycondensation endows the copolymer with an M-n of 2300 (by GPC, polystyrene standards) and good solubility in organic solvents. The fluorescence spectra of the copolymer measured with tetrahydrofuran solution shows an emission maximum (lambda(max)) at 372.8 nm, whereas for the film the maximum shifts to 436.6 nm.NiCl2(bpy) catalyzed polycondensation between p-dibromobenzene and m-dibromobenzene has been carried out under various conditions.
