Abstract

Abstract : Three 2, 4-thiazolidinedione based macrocycles, which are very good Fe 3+ sensors in aqueous-ethanol medium, have been synthesized. X-ray crystallography, DFT calculations and MEP analysis have been used for their structural confirmation and for understanding their behavior towards Fe 3+ . Abstract : A new class of three 2, 4-thiazolidinedione based macrocycles (3a–c ) have been synthesized and then characterized from spectral data and X-ray crystallography. The fluorescence quenching of the compounds caused by the addition of nineteen separate metal cations to their solutions in ethanol–water (3 : 1) was investigated, when it was observed that among the cations, the response to Fe 3+ was distinctive. Again, among the macrocycles, 3c gave the best result.
