Their structures were characterized and analyzed by X-ray single crystal diffractometer and infrared spectrometer. At the same time, the fluorescence properties and thermal stabilities of three MOFs and electrochemical behavior of MOFs material-modified glassy carbon electrode were measured by fluorescence spectrometer, thermogravimetric analyzer and electrochemical workstation. The results indicated that three kinds of MOFs have better fluorescence intensity and thermal stability than ligands. The prepared [Co (tdc) (phen)]n modified glassy carbon electrode showed stronger cyclic voltammetry response than the bare glassy carbon electrode for potassium cyanide solution and pH = 5 PBS solution containing 1.0mmol/L NaNO2. It is expected to be used as a modifier in modified glassy carbon electrodes. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书附件1附件1 -->
