摘　　要：选用4,4′,4′-(1,3,5-三嗪-2,4,6-三基)三苯胺和2,5-二乙烯基-1,4-苯二甲醛通过机械研磨法制备得到了一种新型的醛氨共价有机骨架(COF-LY)。通过粉末X射线衍射(PXRD)、傅里叶变换红外光谱(FT-IR)、热重分析(TG)以及氮气吸附-脱附曲线等表征证实了其结构、热稳定性以及多孔性。在77K时氮气吸附测试结果表示,该材料的比表面积为220m^(2)/g。Herein,we employ 4,4′,4′-(1,3,5-triazine-2,4,6-triyl)trianiline and 2,5-divinylterephthalaldehyde through mechanical grinding method to synthesize a novel covalent organic frameworks named COF-LY.Its structure,thermal stability,and porosity were confirmed by the powder X-ray diffraction(PXRD),Fourier transform infrared spectroscopy(FT-IR),thermogravimetric analysis(TG),and N_(2)adsorption-desorption curves.The results of N_(2)adsorption tests at 77K revealed that the BET surface area of the material was 220 m^(2)/g.
