摘　　要：通过改进的合成方法制备4,4′,6,6′-四叠氮基偶氮-1,3,5-三嗪(TAAT),总产率为82.1%。采用DSC、IR、NMR、元素分析等对TAAT和中间产物进行了表征,并对其单晶结构进行了分析。以TAAT为前体,采用热解法制备出碳氮比非常接近理论值的C2N3和C3N5氮化碳纳米材料。推测出TAAT可能的热解过程及C2N3、C3N5氮化碳纳米材料的生成机理。4,4′,6,6′-Tetra（azido）azo-1,3,5-triazine（TAAT） was synthesized by an improved synthesis method with the yield of 82.1%.DSC,IR,NMR,elemental analysis as well as crystal structure diffraction were used to characterize the TAAT and intermediate products.C2N3 and C3N5 whose N/C ratios highly resembled the theoretical peers were prepared by pyrolysis from TAAT.The mechanisms for TAAT pyrolysis and C2N3/C3N5 generation were discussed.
