A multi-responsive supramolecular polymer, β-CD-(PNIPAAm)4-Azo-(PMAA)7, is demonstrated here. This amphiphilic polymer can be achieved by altering the pH or temperature of a solution of the supramolecular polymer system. Absorption and emission spectroscopy, solution transmittance, dynamic light scattering (DLS), and transmission electron microscopy (TEM) were applied. It was found that β-CD-(PNIPAAm)4-Azo-(PMAA)7 can self-assemble into inverse spherical polymeric nanoaggregates and can then disassemble reversibly under the irradiation of UV light due to the trans-to-cis isomerization of the azo groups. The resulting supramolecular polymer is demonstrated to have useful properties, including self-aggregation, supramolecular gelation and stimulus-responsive behavior.

Hollow mesoporous silica nanoparticles (HMSs) were modified by β-cyclodextrin via a "click" reaction, an amphiphilic copolymer with a trans-azobenzene structure was then assembled onto β-cyclodextrin to cover the surface of the HMSs. The prepared nanocomposites can release drugs in a "release-stop-release" manner by converting light irradiation. This journal is The Royal Society of Chemistry 2012.

A fundamental challenge in nanomaterial science is to facilely fabricate nonspherical polymersomes. Here, several kinds of novel tubular polymersomes were fabricatedviaself-assembly of amphiphilic azobenzene-containing block copolymers. Besides, their shape could be tuned by multiple approaches including changes in the chemical structure, self-assembly conditions and external stimuli.
