title: Encapsulation and selective recognition of sulfate anion in an azamacrocycle in water.
abstract: Structural characterization of a sulfate complex with an azamacrocycle suggests that one sulfate is encapsulated in the macrocyclic cavity with eight hydrogen bonds; a significant selectivity of the host was observed for sulfate over halides, nitrate and perchlorate as evaluated by (1)H NMR studies in water.
