✦ Synopsis
In order to examine the molecular recognition effect of a three-dimensional hydrophobic cavity, seven β-cyclodextrin derivatives (1-7) bearing hydrophobic substituents on the primary side, and three structurally related calixarene derivatives (8-10) were synthesized and used as coating materials for a piezoelectric chemical sensor to detect some aliphatic amines in the gaseous state. The results obtained indicate that these synthetic receptors show considerable sensitivity and selectivity toward the analytes. It is interesting that the cyclodextrins and calixarenes show distinctly different sens- [a
