title: Hybrid cavitand-resorcin[4]arene receptor for the selective binding of choline and related compounds in protic media.
abstract: [structure: see text] A hybrid cavitand-resorcin[4]arene receptor capable of displaying pH-modulated binding affinity toward trimethylalkylammonium ions is proposed as an alternative to the low selectivity exhibited by other receptors used in supramolecular fluorescent sensor systems for choline.
