title: A luminescent silver-phosphine tetragonal cage based on tetraphenylethylene.
abstract: A novel phosphine-based tetragonal cage has been assembled from a tetraphenylethylene (TPE)-based tetraphosphine and Ag(+) ions. The cage structure is maintained both in solutions and in the solid state. emits strong fluorescence not only in dilute solutions but also in aggregated states. The turn-on fluorescence of TPE-P4 in dilute solutions is attributed to the formation of . shows potential as a fluorescent sensor towards anions and olefin compounds, which arises from binding of the guest anions/olefin compounds by its labile silver centres.
