摘　　要：以2,4-二氨基-6-甲基-1,3,5-三嗪和间苯二甲酸为原料合成了一例有机超分子材料,并测定了其单晶结构。该材料结晶于三斜晶系,空间群为P-1,晶胞参数为a=10.340 3(8)A,b=10.895 3(10)A,c=10.976 5(8)A,α=82.099(7)°,β=63.882(7)°,γ=68.051(8)°。两种原料分子之间发生了质子转移,相互之间存在着丰富的氢键作用,为整个体系提供了一个刚性的环境。发光光谱测试表明,该材料具有绿色室温磷光发射,且发光寿命长达1.32 s。An organic supramolecular material was synthesized from 2,4-diamino-6-methyl-1,3,5-triazine and isophthalic acid.Its single crystal structure was determined by X-ray diffraction analyses.The material was crystalline in triclinic system with space group P-1,cell parameters are a=10.3403(8)Å,b=10.8953(10)Å,c=10.9765(8)Å,α=82.099(7)°,β=63.882(7)°,γ=68.051(8)°.Proton transfer occurs between the two raw material molecules,and there are rich hydrogen bonds between them,which provides a rigid environment for the whole system.The luminescence spectrum test shows that the material has green room temperature phosphorescence emission,and the phosphor life is 1.32 s.
