环丙沙星–铜配合物的湿敏性质研究
|
Abstract:
近年来有机–无机杂化配位化合物作为湿敏传感器异军突起。常温下合成了环丙沙星–铜配合物(CIF-Cu)，通过X射线单晶衍射对其进行了晶体结构表征，并对其湿敏性质进行了测试。结果表明，该晶体单元结构为[Cu(CIF)(H2O)3]SO4？2H2O，配合物为二维超分子网络，其具有大量裸露的可以与水分子形成氢键的-O-、-N-、-F-等活性位点，在中高湿条件下，阻抗随湿度变化曲线线性关系良好，响应时间仅为13 s，湿敏性能优异。该材料的开发为湿敏传感器的应用提供了良好的候选材料，同时为新型传感技术的研发开拓了新的方向。
In recent years, as humidity sensor, metal-organic coordination materials become more popular. Ciprofloxacin-copper coordination (CIF-Cu) was synthesized at room temperature. Its crystal structure was characterized by X-ray diffraction and its humidity sensitivity was tested. The results show that [Cu(CIF)(H2O)3]SO4？2H2O is a kind of 2D super-molecular. Under middle and high humidity, the linearity of impedance-relative humidity curve of CIF-Cu is good, and the response time is only 13 s. The development of this material provides a good candidate material for the ap-plication of humidity sensor, and opens up a new direction for the development of new sensing technology.
