چکیده انگلیسی
Synthesis and characterization of three novel Schiff bases based on calix[4]arene are described. The synthesis of these compounds had been achieved by the condensation of salicylaldehyde derivatives with the amine group of upper rim of de-butylcalix[4]arene in ethanol. The structures of new compounds were confirmed on the basis of IR, 1H NMR, 13C NMR, MS and elementary analysis. Photochromic properties of compounds were studied in CH3CN by UV/vis and fluorescence spectra. These Schiff base–calix[4]arene can be used in certain ‘supermolecular electronic devices’ through combining the photochromic behaviors with others such as non-linear optical or charge transfer properties.
