二苯乙二酮苯甲酰腙的合成、晶体结构及荧光性

摘要

The 1,2-diphenyl ethanedionc benzohydrazide was synthesized by the reaction of 1,2-diphenyl ethanedionc and benzohydrazide. The crystal structure of the compound was characterized by X-ray diffraction and Fluorescence. It was assigned to triclinic crystal system, space group P-l, cell data: α = 0.561 0(4) run, a = 99.868(9)°,6 = 1.028 5(8)nm,0 = 98. 775(8)°,c = 1.565 l(12)nm,y = 103.503(8)°, V = 0.847 5( 11) nm3, Z = 2,μ=0.087mm-1,Dc = 1. 350mg/m3, F(000) =364, R1=0.146 l[I>2sigma(I) ] ,wR2 =0.412 3(all data). Fluorescence spectra showed that the compound is a strong fluorescent substances,and can be used as a potential photoactive materials.%由二苯乙二酮和苯甲酰肼通过缩合反应,合成新的酰腙化合物:二苯乙二酮苯甲酰腙.通过X射线单晶衍射和荧光光谱对该化合物进行晶体结构的表征.研究表明,该酰腙为三斜晶系,空间群为P-1,晶胞学数据:a=0.561 0(4) nm,α=99.868 (9)°,b=1.028 5(8)nm,β=98.775(8)°,c=1.5651 (12)nm,=103.503(8)°.V=0.847 5(11) nm3,Z=2,μ=0.087 mm-1,Dc=1.350 mg/m3,F(000) =364,R1=0.1461 [1＞2sigma(1)],wR2 =0.412 3(all data).荧光光谱表明,该化合物的荧光性能较好,可以作为一种潜在的光活性材料.
