We present a method for approximating thermodynamic parameters ΔG(P,T)°, ΔH, and ΔS for the cation exchange process in metal-organic frameworks, as exemplified by Ni(2+) exchange into Zn4O(1,4-benzenedicarboxylate)3 (MOF-5) and Co(2+) exchange into MOF-5 and Zn5Cl4(bis(1H-1,2,3-triazolo-[4,5-b],[4',5'-i])dibenzo-[1,4]-dioxin)3 (MFU-4l). For these examples, we find that the cation exchange process is endergonic and that parameters such as solvent and cation identity impact the thermodynamics.
我们提出了一种用于估算金属有机框架中阳离子交换过程的热力学参数ΔG(P,T)°、ΔH和ΔS的方法，以Ni(2+)交换到Zn4O(1,4 - 苯二甲酸酯)3（MOF - 5）以及Co(2+)交换到MOF - 5和Zn5Cl4(双(1H - 1,2,3 - 三唑并-[4,5 - b],[4',5'- i])二苯并-[1,4]-二恶英)3（MFU - 4l）为例。对于这些实例，我们发现阳离子交换过程是吸热的，并且诸如溶剂和阳离子特性等参数会影响热力学。
