Optical and electrochemical studies of thiacalix[4]arene film supported on Si/SiO2 for ion-sensitive sensor

The present work is motivated by the development of ion-sensitive sensors (suited for aqueous medium) based on functional supported thin film as sensitive membrane. Thin thiacalix[4]arene films was deposited using the technique of thermal evaporation under vacuum to fabricate chemical ion-sensitive field effect transistor (ISFET) microsensors. The aim is to characterize thiacalix[4]arene thin film (morphology, chemical composition) and its optical and electrical properties before and after detection of copper(II) ions.
