Abstract

Calix[4]arene based podands 1a of cone conformation and 1b of 1,3-alternate conformation possessing imine units and bearing anthracene moieties have been synthesized by a 1 + 2 Schiff base condensation in good yields and examined for their cation recognition abilities towards cations such as lithium, sodium, potassium, nickel, cadmium, copper, zinc, lead, silver and mercury ions by UV–vis and fluorescence spectroscopy. The calix[4]arene derivative 1b shows a selective fluorescence enhancement in presence of Cu2+ ions among the various metal ions tested (Li+, Na+, K+, Ni2+, Cd2+, Cu2+, Zn2+, Pb2+, Ag+ and Hg2+ ions). The colour of the solution changes from colourless to light yellow in the presence of Cu2+ ions. The stoichiometry of the complex formed between 1b and Cu2+ was found to be 1:1 as established by Job’s plot.
