Dendrimers containing azobenzene chromophores is a new kind of functional macromolecules. The study on its synthesis and photoresponsive properties is one of the most active research fields in macromolecular science.This article reviews the synthesis
structure and properties of the dendrimers with photoresponsive azobenzene units in the exterior
interior
or throughout the dendritic architecture.The photoresponsive properties are discussed in detail.
