Description

一种双咪唑高氯酸盐的制备、结构及荧光性质
技术领域
本发明属于有机化学、晶体学及光学领域，涉及有机盐类化合物的合成及晶态结构表征。
背景技术
苯并咪唑衍生物是一类结构特殊杂环结构的化合物，分子结构有刚性较强的共平面性，其中咪唑环具有独特的识别配位性能、质子接受性能及共轭酸碱性能，苯并咪唑衍生物享有“生命配体”的称号。同时由于其具有特殊的π⋯π共轭结构，在紫外-可见光区表现出较强的特征吸收，而且这种特殊的结构可以通过氢键、π⋯π堆积和金属离子配位、疏水-疏水作用与生物体内的受体和酶发生反应，具有良好的生物活性、反应活性、高选择性等。苯并咪唑及其衍生物在有机合成中应用范围也十分广泛（R. g. M. Julien Jouanneau,Laurent Gonon, and Ge ´rard Gebel, Macromolecules 2007, 40, 4）。
在2-(1H-咪唑-1-甲基)-1H-苯并咪唑结构中，苯环和苯并咪唑的刚性很大，且咪唑环上的N-H会产生分子间氢键从而增大分子间作用力。因此设计更加新颖的双咪唑化合物，并扩展其功能，不仅挖掘了该物质的价值，更对配位化学及光学的发展起到了推动作用。
发明内容
本发明属于有机化学、晶体学及光学领域，涉及有机盐类化合物的合成及晶态结构表征。
本发明提供一种双咪唑高氯酸盐，分子式为C11H12Cl2N4O8，化学式 [H2IBI]2+ 2ClO4 –。
本发明提供的双咪唑高氯酸盐主要采取以下技术方案：
将高氯酸和2-(1H-咪唑-1-甲基)-1H-苯并咪唑加入甲醇水溶液中并在一定温度下加热，加热一定时间后缓慢降至室温，冷却析出晶体。所得晶体通过单晶X射线衍射方法测量，并在PC机上用SHELX程序包解析确定其晶体结构(图1-图4)。并检测了此化合物的荧光光谱图（图5）。
