| Abstract: | By reacting calix[4]-1,3-aza-crown 2 with 1,6-diisocyanatohexane in “1+2” condensation mode, the first example dumbbell shaped biscalix[4]-1,3-aza-crown 3 was conveniently prepared in yield of 94%. The complexation properties of compound 3 were investigated by UV–vis spectra and 1H NMR experiments. The results showed that compound 3 has good complexation abilities for anions. Compound 3 binded monoacidic anions with 1:2 binding-stoichiometry and binded binary acidic anions with 1:1 binding-stoichiometry. |
