Significance
Ring-expansion metathesis polymerization (REMP) can be used to prepare perfect cyclic polymer chains. Activated ester template A was prepared from 1 using Grubbs cyclic ruthenium-alkylidene catalyst. This template was transformed into a copper(I) click-ready template B. Both templates were post-functionalized to create cyclic gels (e.g., cyclic gel A and B) and cyclic polymer brushes (A, B, B′).
