摘要
合成了一种新型三取代结构的双光子吸收材料1,3,5-三[4-[2-(3-吡啶)乙烯基]苯基]苯(4),通过元素分析、电喷雾质谱、1HNMR和红外对其进行表征。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7.63×10-48cm4.s.photon-1。利用合成的1,3,5-三[4-[2-(3-吡啶)乙烯基]苯基]苯作引发剂,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 TPA material with tri-substituted structure 1,3,5-Tris[4-[2-(3-pyridyl)ethenyl]phenyl] benzene was synthesized.The structure of the compound had been characterized by elemental analysis,electron-spray mass spectra,1H NMR,and IR spectra.UV-Vis absorption,one-photon induced fluorescence and two-photon induced fluorescence were experimentally studied.The two-photon absorption cross-section is as high as 7.63×10-48cm4·s·photon-1.A pulse duration of 200fs and repetition rate of 76MHz,mode-locked Ti∶sapphire laser was used for two-photon microfabrication.Some three dimensional lattices were created by two-photon polymerization of an acrylic eater oligomer using this initiator.The lattice fabricated was observed through a polarization microscope(Olympus,BX-51).It is a potential TPA material.
