Photo-chemistry has attracted widespread attention of researchers due to its easily-operating and environmentfriendly technology. Photo-Induced living/controlled atom transfer radical polymerization and click chemistry (Photo- Induced ATRP/Click) is an effective method to accurately synthesize polymers with various topological structures. In the past decade

photo-induced ATRP/Click technique has been used frequently in the preparation of polymers

and more and more macromolecules with complex structures and special functions have been prepared by the technique. In this paper

the recent development in the field was summarized and the emphases were on the preparation of block

graft

cyclic and other topological polymers through photo-induced ATRP/Click. In addition

the applications of these polymers in pharmaceutical carriers

bio-materials

photo-electrics and thermal-sensitive materials were reviewed.
