Abstract

A xanthone-based chemosensor bears two 2,2′-dipicolylamine-zinc(II) sites and displays changes in the excitation spectrum at three wavelengths upon binding phosphates (see picture). These changes in the signals arise from the coordination rearrangement of the xanthone fluorophore around the zinc centers, which modulates the photophysical property of the chemosensor, thus enabling ratiometric fluorescent analysis. (Graph Presented).
