Abstract
Spun thin films were fabricated using two different calix[4]resorcinarene materials. SPR curves of the calix[4]resorcinarenes along with an uncoated gold layer were determined. Exposure of the calix[4]resorcinarene films to organic vapours led to their adsorption into the thin film with concurrent changes in film thickness and refractive index which caused shifts in the SPR curves. Kinetic graphs were obtained as a result of the repeated exposure of the film to 20–40–60–80–100% of saturated vapour for up to seven cycles. Chloroform, dichloromethane, carbon tetrachloride and trichloroethylene vapours were all utilised for the gas exposures and kinetic curves obtained for each compound. Differences in the film nature and adsorption properties are discussed. Differences in vapour adsorption were noted, with the calix[4]resorcinarenes being most effective at binding chloroform.
期刊介绍：
The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
