摘要: 掺杂微量三价铽离子的邻苯二甲酸锌在紫外光激发下可产生非常强的绿色荧光, 是一种很好的光致发光材料[1, 2]. 邻苯二甲酸锌在热敏变色和彩色热敏记录材料及光电器件透明封装材料等方面也有重要应用价值[3~6]. 它的合成以前都采用溶液反应法, 未见采用固相或半固相反应法的报道. 本文采用半固相反应法合成了无水邻苯二甲酸锌, 用溶液反应法合成了一种具有新的结构、同时含有氢氧根和邻苯二甲酸的邻苯二甲酸锌钾复盐, 用元素分析和热分析法测定了其组成和性质, 用红外光谱和粉末X射线衍射法表征了配位结构和晶体结构。

Abstract: The ZnPht [Pht= o-C6H4(CO2)22-] and double salt Zn9K309(OH)505Pht8.2·0.35H2Pht·4H2O were synthesized by semi solid reaction and solution reaction methods, respectively. Their infrared spectra and TG and DTA curves were measured. The crystal structures were characterized by powder X-ray diffractometry. Both are monoclinic: for ZnPht a =1.1044, b =0.9687, c =2.5949 nm, β =92.19°, for double salt a =1.7138, b =0.8343, c =1.6879 nm, β =113.35°.
