摘　　要：合成了一种新型三取代结构的双光子聚合引发剂1,3,5-三[4-(N,N-二乙氨基)苯基]乙烯基]苯基]苯(4),通过元素分析、电喷雾质谱、1 H NMR和红外谱对其进行表征。测试了紫外吸收光谱、单光子荧光光谱和双光子荧光光谱,并测出其双光子吸收截面为9.87×10-48cm4.s/photon。利用合成的1,3,5-三[4-(N,N-二乙氨基)苯基]乙烯基]苯基]苯作双光子聚合引发剂,以甲基丙烯酸甲酯齐聚物作单体(CN120C80),200fs,76MHz、Ti:sapphire飞秒激光器作光源,进行了三维周期微结构的制作。所合成化合物是潜在应用前景的双光子吸收材料。A novel two-photon polymerization initiator with tri-substituted structure 1,3,5-TrisE4-（N, N-diethyl- amino）phenylethenylphenylbenzene was synthesized. The structure of the compound had been characterized by elemental analysis, electron spray mass spectra, H NMR and IR spectra. UV-Vis absorption, one-photon induced fluorescence and two photon induced fluorescence were experimentally studied. The two-photon ab- sorption cross-section is as high as 9.87 X 10 ＇Scm4 s/photon. A pulse duration of 200fs and repetition rate of 76MHz, mode-locked Ti： sapphire laser was used for two photon microfabrication. Some three dimensional lat rices were created by two-photon polymerization of an acrylic eater oligomer using this initiator. The lattice fab- ricated was observed through a polarization microscope （Olympus, BX-51）. It is a potential TPA material.
