| 中文摘要: |
| 由EDTA二酐和多缩乙二醇出发,合成了一系列具有N-支套索冠醚结构的二异羟肟酸配体(L1H2～L4H2)其及钴(II)配合物(CoL1～CoL4),以IR,1HNMR, MS和元素分析进行结构表征. 测定在在不同温度下CoL1～CoL4的氧加合常数InKO2和热力学参数ΔH0, ΔS0,研究了氮杂冠醚环的大小对配合物氧加合性能的影响. |
| 英文摘要: |
| The dihydroxamic acid functionalized N-pivot lariat ether(L1H2～L4H2)and their Cobalt(II) complexes (CoL1～CoL4)were synthesized starting from EDTA dianhydride and polyethylene glycol. Their structures were characterized by IR, MS, 1H NMR and elemental analysis. The equilibrium constants InKO2 and thermodynamic parameters (ΔH0, ΔS0) for oxygen of CoL1～CoL4 were measured. The modulation of O2-binding capabilities by the size of the aza-crown ring of the ligend were discussed. |
