摘　　要：制备了一种双光子聚合引发剂,反,反-1,4-双(4-’N,N-二丁胺基苯乙烯)-2,5-二甲氧基苯(DBASDMB),利用挥发溶剂法首次获得该化合物的晶体,用四圆X射线衍射法解析了晶体结构。结果表明,该晶体属于三斜晶系,P-1空间群;同时证明引发剂分子是具有很好对称性和平面性的全反式结构。仔细研究了该化合物在不同溶剂下的线性吸收光谱和单、双光子荧光谱,并在同一条件下对其单、双光子光谱进行了比较。在760nm的飞秒脉冲激光辐照下,DBASDMB能够高效地引发聚氨酯类丙烯酸酯齐聚物的聚合反应,成功地制作了一个微结构。A initiator for two-photon photopolymerization, E, E-1, 4-bis[4 ＇-（N, N-di-n-butylamino） styryl]-2,5- dimenthoxybenzene （abbreviated to DBASDMB） has been synthesized. Its single crystal has been obtained by means of volatile solvent and crystal structure determined by a four-circle diffractometer, respectively. The result showed that the crystal belongs to the triclinic space group P-1,at the same tlme,one can see that the molecule is a completely reverse structure which possesses a fine symmetry and a good conjugation. The linear absorption spectra and linear photoluminescence were investigated in various solvents, and the properties of one-photon and two photon fluorescence were compared at the same conditions. Finally, the two-photon polymerization was carried out and a three-dimensional microstructure was fabricated under irradiation at 760nm using a fs laser by DBASDMB initiating polymerization of the oligomer, such as urethane acrylate.
