| 摘要: 以优化的两步一锅反应法合成了生物金属有机化合物Fe（C5H4-CH2-Trp-OMe）2（FcL），通过NMR、HRMS及IR等对其结构进行了表征，利用X射线单晶衍射测定了分子结构。循环伏安法研究表明FcL在0.00~0.90 V电位范围内，给出一稳定的、形态良好的氧化还原峰，这归于化合物中Fc/Fc+电对的氧化还原过程。电化学金属离子识别研究显示FcL在过渡金属离子Zn2+和Cu2+的存在下，导致了配体Fc/Fc+式量电位的显著阳极移动，其△E0'对Zn2+和Cu2+分别为342和335 mV，表明了FcL对Zn2+和Cu2+具有良好的识别能力。 | |

| Abstract: A simple and efficient two-steps one-pot synthetic methodology for the preparation of Fe (C5H4-CH2-Trp-OMe)2(FcL) is described,and FcL was fully characterized by NMR spectroscopic techniques,mass spectrometry (HRMS) and IR.The crystal structure of FcL was determined by X-ray single crystal structure analysis.The cyclic voltammetric behavior of FcL showed one pair of well-defined and stable redox waves in potential range of 0.0~0.9 V at GC electrode,which attributed to the Fc/Fc+ redox process.Electrochemical investigations of FcL have demonstrated that addition of Zn2+ and Cu2+ results in large shifts of respective Fc/Fc+ redox couple to more positive potentials,342 and 335 mV,respectively,and this suggests that FcL has good ability in recognizing of the vital Zn2+ and Cu2+. | |
