Fe(C_5H_4-CH_2-Trp-OMe)_2的合成、晶体结构及金属离子识别性能

Synthesis,Crystal Structure and Electrochemical Metal Cation Recognition Investigation of Fe(C_5H_4-CH_2-Trp-OMe)_2

以优化的两步一锅反应法合成了生物金属有机化合物Fe(C_5H_4-CH_2-Trp-OMe)2(Fc L),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Fc L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Zn^(2+)和Cu^(2+)的存在下,导致了配体Fc/Fc+式量电位的显著阳极移动,其ΔE0′对Zn^(2+)和Cu^(2+)分别为342和335 m V,表明了Fc L对Zn^(2+)和Cu^(2+)具有良好的识别能力。

A simple and efficient two-steps one-pot synthetic methodology for the preparation of Fe（CsH4-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 Cu2vresults 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＋.
