【摘要】 介绍了通过水热合成得到的三种新颖的铜-碘化合物(phen)Cu3I31(phen=1,10-phenanthroline,邻菲咯啉),[Cu(en)2][Cu4(phen)2I6]2(en=ethylenediamin,乙二胺),[Cu(1,3-propanediarnine)2][CuI2]23的结构,并对其进行红外光谱,固体紫外可见漫反射光谱分析。对化合物1的荧光光谱分析表明它在室温下能发出强的橙红色光并具有极长的寿命(τ=1249.91 ns)。此外,我们还运用CASTEP程序对化合物2进行量化计算,所得到的紫外吸收光谱和实际测得值较为吻合。
【Abstract】 Three novel copper-iodide compounds,(phen) Cu3I31 (phen=1,10-phenanthroline),[Cu(en)2][Cu4(phen)2I6]2 (en =ethylenediamine),[Cu(1,3-propanediamine)2][CuI2]23,were succefully synthesized under hydrothermal condition.The structure of these three compounds was determined by the X-ray single crystal diffraction and they were characterized by the FT- IR,UV-Vis DRS.The fluorescent study of 1 shows that it exhibits intense orange-red luminescence with extremely long lifetime (τ=1 249.91 ns) at room temperature.Moreover,we also calculated the UV absorption spectra of compound 2 by CASTEP code,the results of which are in accordance with the experimental value to some extent.
