Metal Complexes of pi-Conjugated Polymers

pi-Conjugated chelating polymers such as poly(2,2'-bipyridine-5,5'-diyl), poly(1,10-phenanthroline-3,8-diyl), and salophen polymers have been prepared by organometallic polycondensations. The obtained polymers form metal complexes with various metal species such as [Ru(bpy)(2)](2+) and CuCl2. Metal complexes of pi-conjugated ligands are also polymerized by dehalogenative organometallic polycondensations. Some of the metal complexes of pi-conjugated polymers exhibit electrical conducting nature and show catalytic activity for redox reactions.
