摘要

A series of new hyperbranched poly(aryleneethynylene)s are synthesized by the copolycyclotrimerizations of tetraynes (I and II) with aliphatic monoynes (A–C) catalyzed by tantalum-

niobium-

and cobalt-based catalysts. All the reactions proceed smoothly and soluble polymers of high molecular weights (Mw up to 3.8  104) are obtained in high yields (up to 97%).
