Reversible helix–random coil transition of poly(m-phenylenediethynylene) by a rotaxane switch

Abstract

Pendant rotaxane switch-tethering poly(m-phenylene diethynylene) was synthesized by the polyoxidative coupling of a rotaxane containing an axle-terminal m-diethynylbenzene group and an optically active crown ether. The reversible helix–random coil transition of the polymer was successfully performed by the positional switching of the rotaxane wheel.
