Mass-Sensitive Solvent Vapor Detection with Calix[4]resorcinarenes: Tuning Sensitivity and Predicting Sensor Effects

摘要

Preorganized calyx[4]resorcinarenes forming vaselike cavi- ties are tested with respect to their chemical sensing capabilities as coatings on mass-sensitive devices. A synthetically modified vaselike host molecule with a definite cavity morphology forms densely packed layers for measurements with a SAW oscillator. In contrast to this detection of surface phenomena with ultrathin layers, QCM resonators require bulky microporous coatings with a high vapor permeability.
