A novel fluorescent nano-chemosensor for Al(III) ions using a new macrocyclic receptor.
A novel macrocyclic chemosensor (L) has been 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 35nm were prepared by nanoprecipitation method. The influence of metal cations such as Na(+), K(+), Cs(+), Mg(2+), Ba(2+), Al(3+), Pb(2+), Cr(3+), Mn(2+), Fe(3+), Fe(2+), Co(2+), Ni(2+), Cu(2+), Zn(2+), Cd(2+), Hg(2+) and Ag(+) on the spectroscopic properties of nano-chemosensor (L) in aqueous buffer solution were investigated by means of emission spectrophotometry. The macrocycle was found to be as an effective fluorescence sensor for Al(3+) ions.
