Abstract

The stereochemistry of calix[4]arenes capped by diamide bridges in the 1,3-position on the lower rim was established by1H and13C solution and solid state NMR. The13C chemical shifts of ArCH2Ar were found to be diagnostic of the cone, partial cone and 1,3-alternate conformations also in the solid state. Two sets of signals appearing in the CP/MAS spectra of 1,3-alternate and partial cone compounds indicate that these molecules occupy inequivalent sites in the elemental cell.
