| 摘 要： | A series of new hyperbranched poly(aryleneethynylene)s are synthesized by the copolycyclotrimerizations oftetraynes(Ⅰand Ⅱ)with aliphatic monoynes(A-C)catalyzed by tantalum-,niobium-,and cobalt-based catalysts.All thereactions proceed smoothly and soluble polymers of high molecular weights(M_w up to 3.8×10~4)are obtained in high yields(up to 97%).

| Abstract: | 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%). |
