Abstract

A “click” polymerization of dialkynes that contain an ester linkages and diazides to has been performed to synthesize various polyesters, termed “click polyesters” with a high $\overline M _{\rm n}$ of 1.0 × 10^4^ to 7.0 × 10^4^ in an excellent yield. This polymerization accompanied a formation of 1,4‐disubstituted triazoles in the polyester main chain by a Cu^I^ catalyst. The triazole ring formation in the polyester main chain leads to improved thermal properties and enhancement of the even–odd effect of methylene chain length of the produced click polyesters. This report is the first report of the application of click chemistry to synthesize a series of polyesters under mild conditions.

A new interesting category of organometallic polyesters based on diarylidenecycloalkanones containing ferrocene derivatives in the polymer main chain has been prepared by interfacial polycondensation of 1,1 '-dichlorocarbonyl ferrocene or 1,1 '-dichlorocarbonyl-4,4'-diiodoferrocene with 2,5-bis ( p
