Functional polydiynes prepared by metathesis cyclopolymerization of 1,7-dihalogen-1,6-heptadiyne derivatives

Abstract

The MCP route used for the polymerization of 1,6-heptadiynes was successfully applied to the polymerization of 1,7-dihalogen-1,6-heptadiynes, and the target polymers were obtained in high yield with high molecular weight and unique UCST behavior.

Room-Temperature Magnetism in the Crystal of a 1,6-Heptadiyne Derivative and the Processable Polymer

“…The polymerization of M1 largely followed the procedures of metathesis cyclopolymerization, as described in literature. [41][42][43] Under the optimized reaction conditions, the poly(1,6-heptadiyne) derivative P1 was obtained in good yield by using transition metal catalyst MoCl5 in ultra-dry 1,2-dichloroethane (DCE) under nitrogen atmosphere, the optimization processes were described in Experimental section and Supporting Information (Table S1).
