摘要
A novel phosphine-based tetragonal Ag4L2 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. Ag4L2 emits strong fluorescence not only in dilute solutions but also in aggregated states. The turnon fluorescence of TPE-P4 in dilute solutions is attributed to the formation of Ag4L2. Ag4L2 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.
