2,2′: 5′,2″-Terthiophene derivative containing benzo-18-crown-6 fragments linked through ethene spacers was synthesized, and its complexation with octane-1,8-diaminium diperchlorate in acetonitrile was studied by spectrophotometric titration, 1H NMR, and mass spectrometry. The 1: 1 stoichiometry of the complex was confirmed by mass spectrometry, and its structure was proposed on the basis of the 1H NMR data.
