摘　　要：报导了一个铁卟啉化合物2的合成与表征.选择了5种潜在的配体:三乙胺(Et3N)、吡啶(Py)、2,6-二甲基吡啶(Lut)、四氢呋喃(THF)和1,4-偶氮双环[2,2,2]辛烷(DABCO)与铁卟啉化合物2进行配位研究;发现单齿配体中Et3N的配位性能最好,Py其次,Lut和THF几乎没有作用,双齿配体DABCO的作用强度比Et3N略差.利用MS光谱和UV-vis光谱对铁卟啉与这些配体配位性能的差异进行了详细的讨论.图9,参23.A iron porphyrin 2 was synthesized and characterized according to the ＂bottom-up＂ method. Its axial coordination properties were deliberately explored by using ESI-MS and UV-vis spectra. Five ligands： triethylamine （Et3N）, pyridine （Py）, lutidine （Lut）, tetrahydrofuran （THF） and 1,4-diazobicyclo [2,2,2]octane （DABCO） were selected to coordinate with iron porphyrin 2. It was found that Et3N can effectively substitute the ligands （Cl- and MeCN ） linked to central Fe atom and Py can only substitute the ligand Cl-. The Lut and THF cannot displace both. Therefore, the ligand DABCO was convenient to form axial coordination polermer. The synthesis and characterization of all compounds was showed, respectively, and the coordination differences of the five ligands with the iron porphyrin were also deliberately discussed in the report. 9figs., 23refs.
