摘      要：The preparation of monodisperse azobenzene(Azo)polymer microspheres by dispersion polymerization was *** photo-induced fusion of Azo polymer microspheres was successfully achieved during the process of reversible trans-cistrans photoisomerization of Azo units,and induced various unique“microsphere molecularclusters or“microsphere polymers.Encouraged by this interesting phenomenon,microsphere clusters of different topological structures were stabilized by the in situ acetal cross-linking *** photo-induced fusion polymerization of monodisperse polymer microspheres provides a new strategy for designing photo-responsive clusters and allows for control over the mechanical properties of microspheres with high spatiotemporal resolution.
