Reversible formation of multiple stimuli-responsive polymeric materials through processing control of trifunctional amphiphilic molecules.

Abstract

A nonionic amphiphile consisting of thermo-responsive tetraethylene glycol chains, redox-responsive thiol groups, and photo-responsive anthracene units was developed. By combining the thermal and redox stimuli in water and bulk to control the assembling processes, two pairs of polymeric materials possessing contrasting responses to thermal treatment and photoirradiation were prepared.
