title: Selective binding and fluorescence sensing of diphosphate in H2O via Zn(2+)-induced allosteric regulation of the receptor structure.
abstract: A terpyridine-based receptor featuring two [9]aneN(3) units is able to selectively bind and sense diphosphate over mono- and triphosphate in aqueous solution at pH 7, thanks to the conformational change of its structure induced by Zn(2+) coordination to the polypyridyl moiety.
