Abstract: A polymer containing azobenzene side chain was synthesized used 4,4′-two amino two methoxy phenyl ether,4′-methoxy-2,4-two aminoazobenzene and 3,3′,4,4′-biphenyl dianhydride as monomers,and N,N-dimethylacetamide as solvent.The structure of polymer was characterized by infrared spectroscopy (FT-IR),ultraviolet visible absorption (UV-Vis) spectroscopy,nuclear magnetic resonance (1H-NMR),high performance liquid chromatography (GPC),thermal gravimetric (TGA) and atomic force microscopy (AFM).A kind of grating material which can be used to record multiple sets of different information at the same position was prepared by using P polarized laser as interference light source.The results showed that the polymer had a high degree of alignment,excellent thermal stability and good mechanical properties.Even when the laser light source was turned off,the optical recording remained unchanged,showing a permanent recording effect.
