[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, 偽 / C = 73.123) 擄, 尾 = 83.823) 擄, 尾 = 69.59N ~ (3N) 路, and the samples after heat treatment at 200 鈩,
