Hemicryptophanehost as efficient primary alkylammonium ion receptor

Abstract

Hemicryptophane 3 was found to be an efficient and selective primary alkylammonium receptor. Binding constants are 1000-fold higher than those previously reported for hemicryptophane hosts. Efficient complexation of dopamine emphasizes the use of this host for neurotransmitter complexation. Density functional theory calculations were performed and highlight host–guest complementarities.
