Clathrate tetraldehyde cavitand: Single-crystal structure and NMR study

Article abstract of DOI:10.1080/10610278.2015.1102261

The tetraldehyde cavitand, C₁₀₀H₈₈O₂₀, was synthesised as the penultimate stage of a procedure to obtain cavitand-capped porphyrins. The complete structural characterisation was performed by single-crystal X-ray diffraction studies, NMR and IR spectroscopy. The inclusion phenomena of the solvent molecules were confirmed using NMR spectroscopy. The structure is the first example of a clathrate having an aromatic tetraldehyde cavitand grown as a single crystal with acetonitrile at the lower rim of the molecule and methanol at the upper rim of the molecule.
