Oxo-bisurea-functionalized macrocycles, cycle 1, cycle 2, and cycle 3, were synthesized by a stepwise coupling approach. Absorption studies reveal that cycle 2 and cycle 3 can bind with halide anions in a 1:1 stoichiometry with binding constants of 105~108 L·mol-1. 1H NMR titration experiments show that urea groups are the binding sites and play important roles in the binding strength.

Key words: macrocycle, urea, halide anion-responsive, absorption
