摘要：

Addition of 1,3,5-triethynylbenzene or 1,2,4,5-tetraethynylbenzene to a reaction system containing pi-conjugated oligomeric poly(arylene ethynylene) gives polymers with very high molecular weights, which are considered to have star-type structures. The polymers exhibit st photoluminescence peak at 457 +/- 2 nm with a quantum yield of 35 +/- 4%. (C) 1997 Elsevier Science S.A.
