The entropic route… to boost molecular recognition in gas sensing has been successfully implemented. In their Full paper on page 5772 ff. , E. Dalcanale et al. validate this approach for the phosphonate cavitands/alcohol receptor–analyte pairs in mass sensors. The cover shows the molecular structure of a tetraphosphonate cavitand–methanol complex, in which the guest hydrogen bonding is equally distributed among four isoenergetic positions. The underlying graphics illustrate the ESI‐MS experiments and the QCM responses supporting the enhanced complexation at the gas–solid interface.
