| Abstract: | A new tetra‐N‐substituted tetraazacrown ether derivative, 4,7, 13,16‐tetra (2‐cyanobenzyl)‐1, 10‐dioxa‐4,7,13,16‐tetraazacyclooctadecane, C44H48N8O2, has been synthesized and structurally characterized. It crystallizes in the monoclinic system, space group P21/c with a = 1.1176(3) nm, b =2.1906(7) nm, c = 0.8430(3) nm, V = 2.0132(10) nm3, β = 102.740(5)°, Z =4, Dc = 1.189 g/cm3, final R1, = 0.0460, wR2 = 0.0803. The liquid membrane transports of alkali metal cations using the new macrocycle as the ion‐carrier were also studied. Compared with some macrocyclic ligands, our newly synthesized lig‐and showed a good selectivity ratio for Na+/Li+. |
