Synthesis and characterization of norbornene polymers containing azobenzene chromophore
关键字：Photorefractive polymer, ROMP, Azobenzene chromophore
Two kinds of norbornene monomers containing azobenzene chromophore were synthesized, and then their ring-opening metathesis polymerization gives two corresponding novel polymers that are potentially good materials for photorefractive applications. These&n...
