Host–Guest Complexes of Oligopyridine Cryptands: Prediction of Ion Selectivity by Quantum Chemical Calculations

“…[28,29] This is surprising since different cryptand/cryptate or crown ether-solvent combinations have been investigated, [30][31][32][33][34] especially with respect to their transport properties [35] or ion conductivity and potential applications in batteries and capacitors, [36] while parallel alkali and alkaline-earth ion complexes with phenanthroline and bipyridine moieties have also been studied. [37] In a recent report we demonstrated that ion selectivity can be studied by quantum chemical methods for [2.2.2] and smaller homologues.…”

31P NMR study of the stoichiometry and stability of several mercury(II) halides with a phosphorus ylide in different solvents

“…It has been well documented that the solvating ability of the solvent, as expressed by the Guttmann donor number [35], plays a key role in different complexation reactions [36][37][38][39]. DMSO is a solvent of relatively high solvating ability (DN = 29.8) which can compete with the ligand and counter ion for metal.…”

1H-NMR study of the stoichiometry and stability of the Ba2+, Sr2+, Hg2+, Pb2+, K+, Ag+, and Tl+ complexes with a new macrocyclic diamide in acetonitrile–nitrobenzene solvent mixture

“…As demonstrated in Table 2, the stability of the complexes increased by increasing the amounts of nitrobenzene in the mixed solvent. The solvating ability of a solvent was expressed by the Guttman donor number [22][23][24][25]. It is well known that the solvating ability of a solvent plays an important role in different complexation reactions [22][23][24][25].…”
