Abstract:

Several novel Schiff base macrocyclic compounds containing thiophene were synthesized from diethyl 3,4-dialkoxythiophene-2,5-dicarboxylate, cyanuric chloride, diethylamine and p-nitrophenol by reduction, oxidation, substitution and cyclization, and their structures were characterized by IR, NMR and electrospray ionization-mass spectrometer(ESI-MS). The studies on their UV-Vis absorption spectra show that Schiff base macrocycles 6―10 have selective recognition for Fe3+.

Key words: Ion recognition, Macrocyclic compound, Schiff base, Thiophene
