摘要
以硼酸和有机胺为原料在水溶液体系中合成了一种有机模板硼酸盐[C6N2H18]0.5[B5O6(OH)4](1a),通过X射线单晶衍射仪对其晶体结构进行了检测。此外,对其进行了元素分析、X射线粉末衍射、红外光谱、热重差热分析及固态荧光光谱等表征。结果表明,该化合物属单斜晶系,空间群为P21/n,晶胞参数为a=0.8593(2)nm,b=1.4015(4)nm,c=1.0293(3)nm,β=104.723(3)°,V=1.1989(6)nm3,Z=4。阴离子基团[B5O6(OH)4]-通过强的氢键连接形成具有三种不同形状孔道的新颖三维超分子骨架结构。该化合物在波长为248 nm的激发光下,发射出最大发射波长为375 nm的紫外光。对化合物进行不同温度的热处理后,其荧光性质发生了明显的变化。
An organic templated borates [C6N2H18]0. 5[B5O6（OH）4]（1a） were synthesized by boric acid and 1,6-diaminohexane in aqueous solution and structurally characterized by single-crystal X-ray diffraction. In addition, the borate had been characterized by elemental analysis, powder X-ray diffraction,FTIR,TG-DTA and photoluminescence spectroscopy. The results show that its single crystal X-ray diffraction data showed that this compound crystallizes in the monoclinic system with space group P21/ n,a = 0. 8593（2） nm,b = 1. 4015（4） nm,c = 1. 0293（3） nm,β = 104. 723（3） °,V = 1. 1989（6） nm3,and Z = 4. The polyanions [B5O6（OH）4]-form a novel 3D supramolecular network with three kinds of channels by extensive hydrogen bonds. The title compound shows a UV photoluminescence with an emission maximum at 375 nm upon excitation at 248 nm,and the photoluminescence can be modified from UV to blue-green by means of a simple heat-treatment process.
