Structural studies and binding properties of pendant diazacoronands—precursors to macrocyclic compounds of planar chirality

Structural studies of pendant diazacoronands having an N-benzoyl, N-acetyl, O-benzyl or O-benzoyl side arm were performed by means of X-ray and temperature-dependent 1H NMR experiments. The energies of macroring flipping process were determined for three pendant diazacoronands. The complexation prop...

Description
Summary:Structural studies of pendant diazacoronands having an N-benzoyl, N-acetyl, O-benzyl or O-benzoyl side arm were performed by means of X-ray and temperature-dependent 1H NMR experiments. The energies of macroring flipping process were determined for three pendant diazacoronands. The complexation properties of pendant diazacoronands toward the alkali metal cations (Na +, K +, and Rb +) were estimated by ESI-MS experiments. [Display omitted]
