Cross-coupling reactions for preparation of π-conjugated polymers

Various π-conjugated aromatic polymers have been prepared by utilizing organometallic CC coupling reactions. The π-conjugated polymers include poly(thiophene), poly(3-alkylthiophene), poly(pyridine), and poly(2,2′-bipyridyl). Some of the polymers form metal complexes, which show catalytic activity for redox reactions.
