Fabrication of picoline amide-based calixarene Langmuir-Blodgett thin film for volatile organic vapor sensing application
Picoline amide-based calixarene molecule was the first time deposited onto gold substrate as an active layer by using Langmuir-Blodgett (LB) coating technique. UV-visible, atomic force microscopy, and surface plasmon resonance (SPR) technique were used to control monolayer quality. The sensing properties were investigated by exposing the LB thin film to different percentage of organic VOCs vapors such as acetone, benzene, chloroform, ethyl acetate, and methanol in air-VOCs mixture. SPR results showed that this calixarene molecule is a good candidate with a fast and reversible sensor response for VOCs sensing applications.
