Comparative computational and thermodynamic study of cation complexation by tetra-O-2-oxopropyl-substituted calix[4]arene atropisomers.
The binding of alkali and alkaline earth metal cations by 1,2-alternate (L12) and 1,3-alternate (L13) conformational isomers of a lower-rim calix[4]arene ketone derivative was investigated in vacuo and in explicit acetonitrile and methanol solvents by means of classical molecular dynamics simulations and quantum chemic...
