C1–C4 alcohol–cavitand complexes

Crystal structures of two of the six cavitand-alcohol complexes. Geometric parameters describing the host-guest interaction, such as the H bond
length (Oalc⋅⋅⋅O=P) and distances of the hydroxyl and methyl groups from the mean plane of O atoms of P=O groups are reported in the top and
in the side views, respectively.

The crucial parameter to define the success of a given sensor is therefore selectivity, and for this reason the strategy to prepare the sensing material following the principle of supramolecular chemistry has quickly gained increasing importance. Here a new solid-state fluorescent sensor based on phosphonate cavitand for detecting short-chain alcohols in the gas phasehas been investigated.
