Abstract
Oxacalix[3]arenes exhibit transient binding to Na
+
, K
+
and Ca
2+
, with a strong preference for Na
+
, as determined by a quartz crystal resonant sensor technique. Computational models for the behaviour indicate that the preference for Na
+
is due to the depth to which that cation is drawn into the macrocycle's central cavity.
