摘要: 合成了双光子聚合引发剂{4-[2-(4-溴苯基)-乙烯基]苯基}-二苯基胺(BVPDA),并测定了其晶体结构.结果表明,BVPDA为三斜晶系,P1空间群,a=1.0834(3)nm,b=1.5625(2)nm,c=1.9640(2)nm,α=92.807(8)°,β=103.647(10)°,γ=106.676(13)°,V=3.0705(10)nm3,Z=6,T=293(2)K,Dc=1.383g/cm3,R1=0.0735,wR=0.1063.用1HNMR谱、13CNMR谱及元素分析进行了表征.测试了紫外吸收光谱、单光子荧光光谱、单光子荧光寿命和双光子荧光光谱.在760nm的飞秒脉冲激光激发下,BVP-DA发出较强的上转换荧光,荧光峰位于462nm.以BVPDA作引发剂,加入丙烯酸酯型齐聚物(CN120C80),用Ti:sapphire飞秒激光器作光源,制作了一个三维周期性微结构.

Abstract: A new two-photon photopolymerization initiator {4-[2-(4-bromophenyl)vinyl]phenyl}-diphenyl-amine(BVPDA) was synthesized and characterized by 1H NMR, 13C NMR and elemental analyses. The crystal structure was characterized by X-ray diffraction structural analyses. BVPDA belongs to the triclinic space group P1 with a=1.083 4(3) nm, b=1.562 5(2) nm, c=1.964 0(2) nm, α=92.807(8)°, β=103.647(10)°, γ=106.676(13)°, V=3.070 5(10) nm3, Z=6, T=293(2) K, Dc=1.383 g/cm3, R1=0.073 5 and wR=0.106 3. The linear absorption, one-photon fluorescence, one-photon fluorescence lifetime and two-photon fluorescence are experimentally studied. When pumped with 760 nm laser irradiation, BVPDA indicates a strong two-photon induced fluorescence of 462 nm. A microstructure using BVPDA as the initiator was fabricated using BVPDA as the initiator under irradiation of 200 fs, 76 MHz Ti:sapphire femtosecond laser at 760 nm.
