A Fully Photoreversible Supramolecular Polymer Having a Diarylethene Photoswitch

Abstract The particle size of a supramolecular polymer composed of a diarylethene photoswitch and two quadruple hydrogen-bonding sites having C17 chain changes photoreversibly in tetrahydrofuran at room temperature, while that in a CHCl3 solution is not photoreversible but is reversible with the assistance of heat.
