Adsorption properties of thin nanostructured films of tret-bytylcalix[n]arenes (n = 3, 4, 5, 6, 8) with thickness of about 200 nm to vapors of different organic solvents are investigated. Two methods were used for adsorption measurements - mass-sensitive quartz microbalance and interference colorimetry. Gas sensitive, selective and regenerative parameters of the used calixarene films as sensitive materials for chemical sensors were investigated. It is shown that the calix[5]arene films are most sensitive for detection of chlorine organic compounds. The comparative analysis of responses of quartz microbalance and optical sensor elements for each of the explored sensitive films have been carried out.
