The inclusion of ethylammonium, N-methylpyridinium cations and native L-α-amino acids by the watersoluble pentasulfonatocalix[5]arene 1 has been investigated at neutral pH by 1H NMR. The complexation behavior has been compared with that of the homologous tetrasulfonatocalix[4]arene 2. Unlike host 2, host 1 exhibits high selectivity in the recognition of the investigated guests.

Abstract
The inclusion of ethylammonium, N-methylpyridinium cations and native L-α-amino acids by the watersoluble pentasulfonatocalix[5]arene 1 has been investigated at neutral pH by 1H NMR. The complexation behavior has been compared with that of the homologous tetrasulfonatocalix[4]arene 2. Unlike host 2, host 1 exhibits high selectivity in the recognition of the investigated guests.File in questo prodotto:
