Cu II与大环五胺1,4,7,10,13-戊-氮杂环十五烷(L 1),1,4,7,10,13-戊-氮杂环十六烷(L 2)之间形成配合物的平衡和动力学,和1,4,7,11,14-戊-氮杂环庚烷(L 3)已进行了研究。用极谱法确定了形成1:1配合物的热力学函数:分别对于L 1,L 2和L 3,log K C u L 28.3、27.1和23.8,–Δ H 32.9、32.7和27.2 kcal mol –1和ΔS 22、14和18 cal K –1 mol–1(在/ 0.2 mol dm –3和25°C时)。与四胺的熵有利的大环效应相反,由五胺的环化引起的大的稳定性增强归因于有利的焓因子。动力学研究已经建立了乙酸盐缓冲液中络合物形成的速率规律,即d [CuL] / d t = k 2 H [Cu(O 2 CMe) + ] [H 2 L 2+ ] + k 3 H [Cu(O 2 CMe) + ]
