Název v původním jazyce

"Turn on/off" proton transfer based fluorescent sensor for selective detection of environmentally hazardous metal ions (Zn2+, Pb2+) in aqueous media

Popis výsledku v původním jazyce

Sensing ability of fluorescence based chemosensor: Indole-7-carboxaldehyde (I7C) for environmentally hazardous metal ions (Xn+ = Zn2+, Pb2+, CO2+, Ni2+, Cu2+, Cd2+, Cr3+, and Fe3+) has been investigated. Based on excited state proton transfer (ESPT) phenomenon, the sensing capability of I7C is verified experimentally (UV-vis, FTIR, NMR) and theoretically (DFL TD-DFT) in aqueous media. Chemical hardness (eta), electrophilicity (omega) and electronic chemical potentials (mu) confirm the selective reactivity of I7C (N-c and N-t conformers) in the presence of metal ions by the formation of (1:1) metal ion: I7C complex (M-x, M-x*). M-x, M-x* are found to display excellent sensing capability for Zn2+ and Pb2+ ions. "Turn-On" response for Zn2+ is observed through the appearance of a new enhanced fluorescence at similar to 430 nm. By strong blue emission I7C establishes its strong candidature as "blue emitter". "Turn-Off" response is observed for Pb2+ through the quenching of the existing fluo
