| Abstract: | Computer simulation of different structures of adsorption complexes formed by gas adsorption on organic layers with various functional groups was carried out. On the basis of simulation results, we chose 2-(4′-dimethylaminophenyl)-4,4,5,5-tetramethylimidazoline-3-oxide-1-oxyl as a substance possessing high selectivity toward SO2. Simulation results were confirmed experimentally in the studies of adsorption by means of ellipsometry and quartz microbalance. |
