Phasing up to complex problems : A thermodynamic approach based on solution data has been proposed for the determination of the stability of gas complexes and elucidation of the selectivity of gas binding. Stability constants, reaction enthalpies, and entropies for the complexation of gaseous guests ( n ‐alkylamines) by solid macrocyclic hosts (β‐cyclodextrin, cucurbit[6]uril) were calculated by using the Born–Haber type cycle (see picture).
