【摘要】：本论文采用传统的水热／溶剂热法和溶液法,以硼酸、3-硝基苯硼酸、金属盐、DMF以及有机胺为原料,成功合成了四种模板硼酸盐。用X-射线单晶衍射仪对四种化合物进行晶体结构表征,对四种化合物进行了元素分析、红外、热重、X-射线粉末衍射四种基本的测试分析。同时对化合物1进行变温热处理,并对处理后的样品进行了X-射线粉末衍射、红外以及荧光光谱分析,探讨了热处理对化合物的荧光性质的影响；研究了化合物2和4的铁电性,在硼酸盐领域第一次对化合物4进行了薄膜铁电测试；化合物3的是少见的手性的沸石结构硼酸盐。主要研究内容如下：化合物1属于三斜晶系,分子式为[C9H14N][B506(OH)4],空间群为P1(No.2),晶胞参数为：1:9.2635(19)A,b=9.7473(19)A,c=9.806(2)A,α=73.12 (3)°, β=83.82(3)°,β=69.59(3).,经过200℃热处理的样品在波长为379nm激发光的激发下发出437nm的光。化合物2属于单斜晶系,分子式为：Ni(en)3·Hen·[B9013(OH)4]·H20,空间群为Pn(NO.6).晶胞参数为：a=10.9982(18)A,b=10.8439(17)A,c=11.7551 (19)A, β:91.84(O)°,化合物2是目前报道的第一个多铁性的模板硼酸盐和第一个由不同结构单元组合的手性链状硼酸盐。化合物3属于四方晶系,分子式为：Zn(1,3-DAP)[B407],空间群为P43212(No.96),晶胞参数为：a=8.670(4)A,b=8.670(4)A,c=12.722(13)A,α:90.00°, β=90.OO°,γ=90.00°,根据目前报道,化合物3是一种少见的螺旋状硼酸锌沸石骨架材料。化合物4属于单斜晶系,分子式为：[B506(OH)4][C6H15N2],空间群为：Cc(NO.9),晶胞参数为：a=9.786(4)A,b=20.930(9)A,c=14.577(6)A, a=90.00°,β=94.406(5)°,γ=90.00°,通过优化实验方案,成功制备了化合物4的薄膜并对其进行了薄膜铁电表征。
[Abstract]:In this paper, four kinds of template borates were successfully synthesized by hydrothermal / solvothermal method and solution method, using borate 3-nitrophenyl boric acid, metal salt DMF and organic amine as raw materials. The crystal structure of four compounds was characterized by X-ray single crystal diffractometer. The four compounds were characterized by elemental analysis, IR and thermogravimetric X-ray powder diffraction. At the same time, compound 1 was heat-treated at varying temperature, and the treated samples were analyzed by X-ray powder diffraction, IR and fluorescence spectra. The effects of heat treatment on the fluorescence properties of the compounds were discussed. The ferroelectric properties of compounds 2 and 4 were studied and the thin film ferroelectric test of compound 4 was carried out for the first time in the field of borates. The main contents of the study are as follows: compound 1 belongs to a triclinic system, its molecular formula is [C9H14N] [B506(OH)4], the space group is P1O No. 2N, and the unit cell parameters are: 1: 1: 9: 2635 / 19 A / C 9.7473C / C 9.806U / 2C, 伪 / C = 73.123) 掳, 尾 = 83.823) 掳, 尾 = 69.59N ~ (3N) 路, and the samples after heat treatment at 200 鈩，
