| 摘要: 采用低温溶液法合成了含有二铵阳离子结构的新型二维层状结构的有机/无机杂化钙钛矿材料（NH3C6H12NH3）CuCl4。采用元素分析、红外光谱、X射线衍射和紫外-可见光吸收光谱等手段对其结构与性能进行了表征。结果表明该材料的紫外-可见吸收光谱吸收峰位于285 nm和387 nm，层间距为1.18 nm。二铵阳离子的引入，使有机层+NH3C6H12NH3+与2个相邻的无机框架CuCl42-分别通过较强的氢键结合在一起，排列更为规整，热稳定性更高。与单铵阳离子结构的杂化钙钛矿材料相比，由于不存在两层有机分子层间较弱的范德华力，（NH3C6H12NH3）CuCl4材料的电阻率为1.36×105Ω·cm，比单胺结构的杂化钙钛矿材料的电阻率低3个数量级。 | |

| Abstract: A novel organic-inorganic hybrid material containing diammonium cations, (NH3C6H12NH3)CuCl4 with perovskite structure, was synthesized by low-temperature solution method and characterized by elemental analysis, FT-IR, XRD and UV-Vis absorption spectra techniques. The result shows that the UV-visible absorption peak of this material is located at 285 and 387 nm, with a layer spacing of 1.18 nm. The organic layer +NH3C6H12NH3+ and two inorganic frameworks, CuCl42-, are bound together by strong hydrogen bonds, so more orderly arrangement and good heat stability are obtained. The resistance of (NH3C6H12NH3)CuCl4 is about 1.36×105Ω·cm, three orders of magnitude less than hybrid perovskite that contain single ammonium cation, just because there is no weaker van der Waals force between two layers of organic molecules. | |
