Ullmann type polycondensations in the presence of CuI and a base were carried out to afford network type π-conjugated copolymers. Infrared absorption spectroscopy measurements and surface observation using a scanning electron microscopy are carried out. Electron spin resonance spectroscopy measurements revealed that the cross-linked copolymers thus obtained contain small amount of copper. This polymerization conveniently allows production of network π-conjugated polymers. The polymer can be expected to have thermo-resistance.
