The Cyclization and Functionalization of Styrenic Polymers

摘要

Macrocyclic poly(styrene) and poly(4-acetoxystyrene) have been successfully synthesized utilizing a highly efficient "click" coupling of a terminal alkyne and azide. This technique has been shown to give high yields of well-defined polymeric macrocycles consisting of molecular weights of 2200 Da and 4200 Da prepared via atom transfer radical polymerization (ATRP). This procedure also enables the facile functionalization of the backbone of the macrocycles in order to incorporate a range functional materials or tune the molecule's physical properties.
