“…The functional groups at the upper and lower rims determine their selectivity in host-guest interactions and physical properties [9][10]. These materials are also used in gas or organic solvent vapor sensors [11][12][13]. Sensor applications of calixarenes have been reported for a few transducer types such as quartz crys-tal microbalances (QCM) [14][15][16] and ISFETs [17].…”

a b s t r a c tWe report on the optimization and characterization of water soluble calix [4]arene derivative as a humidity sensor based on quartz crystal microbalance technique. The moisture adsorption and desorption kinetics of calix[4]arene were investigated. The Langmuir model was used to determine the kinetic parameters such as adsorption, desorption rates and Gibbs free energy between relative humidity between 29% and 78%. Reproducible experimental results were obtained showing that water soluble calix[4]arene films have a great potential for humidity sensing applications at room temperature operations.

a b s t r a c tThis study focuses on the characterization of sulphonated calix[4]arene derivative films coated on a quartz substrate with a thickness of 40 nm by spin coating method for humidity detection. The humidity adsorption kinetics of the sulphonated calix[4]arene films was investigated by quartz crystal microbalance (QCM) technique. The Langmuir model was used to determine the adsorption rates and Gibbs free energy for various relative humidities between 11% and 97%. Our reproducible experimental results show that suphonated calix[4]arene films have a great potential for humidity sensing applications at room temperature operations.

“…The functional groups at the upper and lower rims determine their selectivity in host-guest interactions and physical properties [6,7]. Due to their zeolite-like capacity and selectivity and also simplicity of producing thin films, calixarenes became promising materials for gas sensor applications especially in detecting NO 2 , CO 2 , CO, volatile and humidity gases [8][9][10][11][12][13].…”

This study focuses on the characterization and optimization of calixarene modified carbon nanotube thin films for gas detection. Calixarene molecules were synthesized individually by considering their functional groups to attract the gas. Calixarene modified carbon nanotube based sensors were fabricated using drop-casting method on a quartz crystal microbalance gold electrode. Carbon monoxide, carbondioxide, oxygen and dry air were used as active gases for adsorption process, while high-purity nitrogen gas was used for desorption process. The selectivity and sensitivity of calixarene modified carbon nanotube are investigated in detail. Our experimental results show that functional calixarene modified carbon nanotube coated quartz crystal microbalance sensors are very sensitive and selective to gas of CO 2 at room temperature operation.
