one-pot synthesis of three symmetrical macrocyclic pyridyl urea hosts. X-ray crystal studies were used to confirm the structures of the free hosts and their host·guest complexes with alkali metal ions. These solid-state studies revealed the interactions that were important for binding cations (Li+, Na+, and K+). The affinity of these hosts for alkali metal salts were evaluated in solution (CD3CN), and
