摘　　要：合成了一系列含中心功能基二异羟肟酸开链冠醚L^1H2-L^6H2及其钴（Ⅱ）配合物CoL^1-CoL^6,并以元素分析,IR,1^HNMR和MS进行表征.在不同温度下,测定了钴（Ⅱ）配合物的氧加合常数和热力学参数ΔH^0,ΔS^0.讨论了配体结构、苯环上取代基（X,Y）和添加碱金属离子对配合物氧加合性能的影响.A series of Dihydroxamic Acids Open Chain Crown Ether Containing Central Functional Group L 1^H2- L ^6H2 and their Cobalt（ Ⅱ ） complexes CoL^1 - COL^6 were synthesized and characterized by elemental analysis, IR, 1HNMR and MS spectra. Equilibrium constants and thermodynamic constants （△H^0 and AS^0） for oxygenation of these complexes were measured. The influence of ligand structure, the substituents （X and Y） of the aromatic rings and added alkaline cations on the dioxygen affinities of the complexes was also discussed.
