Amino acid appended diphenylglycoluril-based chiral molecular receptors 2 and 3 have been prepared and their aggregation has been studied in water at various pH's and in chloroform. The binding of several biologically relevant guests with aromatic moieties to these aggregates has been studied with UV-Vis spectroscopy in competition experiments with 4-(4-nitrophenylazo)resorcinol (Magneson) and 2-(4-hydroxyphenylazo)benzoic acid (HABA) as probes. Aggregates of chiral host 2b showed binding of catecholamines and aromatic amino acids in an aqueous environment, as well as discrimination between amino acid enantiomers, and can be considered a mimic for adrenergic receptors.

A new L-lysine appended receptor based on diphenylglycoluril is described. This compound self-assembles to form well-defined tubules in chloroform and vesicles in water. The host molecule strongly binds Magneson both in chloroform and in water, and L-dopa in water mimicking an adrenergic receptor. (C) 2001 Elsevier Science Ltd. All rights reserved.
