由苯并-10-氮杂-15-冠-5出发,经2~4步反应合成了氮杂冠醚取代的单Schiff碱HL1, HL2及其异构体HL3, HL4.并以元素分析,IR, 1H NMR和MS进行了表征.在不同温度下,测定了它们的钴(Ⅱ)配合物的氧合反应平衡常数及热力学参数ΔH°和ΔS°,并与合成的非冠醚类似物CoL25, CoL26和CoL27比较,考察了配体芳环上取代的氮杂冠醚环及其取代位置对氧加合性能的影响.

The azacrown ether substituted salicylaldimine mono-Schiff bases HL1~HL4 were synthesized conveniently from benzo-10-aza-15-crown-5 via 2~4 reaction steps and characterized by IR, MS, 1H NMR and elemental analysis. Moreover, the oxygenation contants (KO2) and thermodynamic parameters (ΔH° and ΔS°) of their cobalt(Ⅱ) complexes were determined in the range of -5℃ to 25℃. The effect of the substituted azacrown rings and their binding sites on dioxygen affinities of the cobalt(Ⅱ) complexes was also discussed as compared with that of crown free analogues CoL25, CoL26 and CoL27.

Key words: benzo-10-aza-15-crown-5, mono-Schiff base, Co(Ⅱ)complex, synthesis, oxygenation
