摘要：
The interaction of hydrogen ions with the series of macrocyclic receptors 2,5,8-triaza[9]paracyclophane, 2,6,10-triaza[ll]paracyclophane, 13,14,16,17-tetramethyl-2,6,10-triaza[ll]paracyclophane, 14,15,17,18-tetramethyl-2,5,8,11-tetraaza[12]paracyclophane and 16,17,19,20-tetramethyl-2,6,9,13-tetraaza[14]paracyclophane has been studied by potentiometry at 298.1 +/- 0.1 K as well as by direct microcalorimetry and H-1 and C-13 NMR spectroscopy. Correlations of the basicity with the atomicity of the macrocycle, the type of chains within the bridge and the nature of the aromatic spacer are envisaged.
