报道了两种新型的咔唑类双光子光聚合引发剂,3,6-双[2-(4-吡啶基)乙烯基]-9-苯基咔唑(1) 和 3,6-双[2-(2-吡啶基)乙烯基]-9-苯基咔唑(2),它们是通过钯催化的Heck偶连反应合成得到,并用元素分析,红外光谱,核磁共振氢谱和电喷雾电离质谱等对它们进行了全面的表征.这两个A-π-D-π-A结构的咔唑衍生物具有很好的单光子和双光子荧光行为,我们也详细研究了它们的溶剂效应和作为双光子引发剂用于微结构的制备,并讨论了它们的引发聚合的机理.
Two new two-photon polymerization initiators derived from carbazole, 3,6-bis [2-(4-pyridyl)ethenyl]-9-benylcarbazole (1) and 3,6-bis[2-(2-pyridyl)ethenyl]-9-benylcarbazole (2) have been successfully synthesized by palladium-catalyzed Heck coupling reaction, and the initiators were fully characterized by elemental analyses, IR, 1H-NMR and ESIMS. The two carbazole derivatives with symmetrical A-π-D-π-A structure exhibit good one- and two-photon fluorescence emission, and the solvent effects have been studied in detail. Two-photon initiating polymerization microfabrication experiments have been carried out and the possible polymerization mechanism was also discussed.
