•A rosamine compound L, bearing a NS2 group, was developed.•Sensor L shows high selectivity for Ag+ in ethanol solutions.•Sensor L is fluorescent turn on sensor for Ag+.
Rosamine derivative, N-(9-(4-(bis(2-(ethylthio)ethyl)amino)phenyl)-6-(diethylamino)-3H-xanthen-3-ylidene)-N-ethylethanaminium hexafluorophosphate, L, bearing an NS2 group as receptor, was synthesized as a turn on chemosensor for silver ion in ethanol solution. Sensor L exhibited high selectivity toward Ag+ in comparison to other metal cations (Cd2+, Cu2+, Hg2+, Na+, Mg2+, Ni2+, Pb2+, Fe3+, and Zn2+). The detection limit for Ag+ was in 10−7 level. The binding properties between silver ion and L were further studied by 1HNMR titration experiments. The chemosensor L can be used as a potential material for silver recognition.
