Multiresponsive smart optical probe based on p-phenylene vinylene backbone is designed for simultaneous sensing of multiple ions, such as Cu2+, Zn2+ and F- at pH 7.4. A rapid color change from colorless to deep yellow is observed upon addition of both Cu2+ and Zn2+ ion. However, under long UV lamp, the green-colored emission of the probe is specifically quenched in the presence of Cu2+, while Zn2+ induces change in the emission color from green to yellow. On the contrary, F-, unlike Cu2+ and Zn2+, does not render any change in visible color, however, an emission quenching, similar to that of Cu2+ addition, was noticed. The binding of metal ions to the central bipyridine core diminishes the ′conformational flexibility′ and facilitates ′ligand to metal ion′ charge transfer. On the contrary, addition of fluoride triggers the cleavage of silyl ether groups and results in the photo-induced electron transfer from free hydroxyl groups to the core aromatic unit. Thus, we can detect as well as discriminate these three ions (Cu2+, Zn2+ and F-) simultaneously by comparing the resp. output signals. Further, a sustainable strategy has been developed for on-site detection of toxic ions using reusable, low-cost paper strips.
