•The fluorescent nano-chemosensor with size about 40 nm was prepared by nanoprecipitation method.•The nano-chemosensor exhibits a significant fluorescent enhancement toward Cs+ in aqueous buffer solution.•The mechanism of fluorescence was based on the due to the photo-induced electron transfer (PET).
A new macrocyclic nano-chemosensor (L) was synthesized and characterized by common spectroscopic methods. Spectral properties of fluorescent macrocycle L were studied either as solution in ethanol or as insoluble nanoparticles in aqueous buffer solution. The nano-chemosensors with size about 40 nm were prepared by nanoprecipitation method. The influence of metal cations such as Na+, K+, Cs+, Mg2+, Ba2+, Al3+, Pb2+, Cr3+, Mn2+, Fe3+, Fe2+, Co2+, Ni2+, Cu2+, Zn2+, Cd2+, Hg2+ and Ag+ on the spectroscopic properties of the chemosensor in aqueous buffer solution were investigated by means of emission spectrophotometry. The macrocycle was found to be as an effective fluorescence sensor for Cs+ ions.
