中文摘要：
设计合成了{4／-[N，N-二（丙烯酸乙酯基）胺基]，4-（吡啶-4-乙烯基））偶氮苯（PAC），通过和甲基丙烯酸甲酯共聚，制备出溶解性能较好的聚丙烯酸酯功能高分子，利用FTIR、NMR、UV等对化合物的结构进行了表征。光限幅实验发现，合成的聚合物对脉宽8ns，波长532nm的激光呈现限幅作用，对聚合物的光限幅机理进行探讨，显示主要为反饱和吸收机理。
英文摘要：
The polyacrylate containing long conjugated azobenzene group were prepared by copolymerization of acrylate containing long conjugated azobenzene group with MMA in N, N-dimethylformamide （DMF） using 2 , 2＇- azobis （isobutyronitrile） （AIBN） as initiator at 70℃. The molecular structures of monomer and polymers were characterized by FTIR,^1H-NMR and UV. The optical limiting property of the polymers in THF solution were investigated with 8ns laser pulses at 532nm wavelength. The results reveal that the polymers display well optical limiting properties and the optical limiting mechanism is mainly originated from the reverse saturable ab- sorption of molecules.
