Dichloromethane, acetone and benzene vapors were selected as a harmful Volatile Organic Compounds (VOCs) to examine the kinetic responses of the calix[4]arene-based LB thin films against to these organic vapors at room temperature. Two calix[4]arene-based chemical sensors were prepared at different thickness values (4 and 8 LB thin film layers) to examine the effect on sensitivity of chemical sensor. The calix[4]arene-based chemical sensor prepared with 4 LB layers was found to be higher sensitive than prepared with 8 LB layers with fast response and recovery times. All kinetic measurements represented that the calix[4]arene molecule used in this study is a promising material for the development of chemical sensor devices at the room temperature with sensitivities between 0.66 and 1.41 percent response ppm−1.}, number={1}, publisher={Selcuk University}
