Abstract
Organic sensor arrays based on photonic crystals of submicrometer polystyrene particles, coated by a layer of polydimethylsiloxane, were studied using diffuse reflectance spectroscopy. The spectral characteristics obtained on instruments with different measurement geometries are compared. The conditions for obtaining the most informative analytical signal of sensor arrays based on photonic crystals are selected. Under the proposed conditions, the kinetic differences in the operation of these arrays upon exposure to nonpolar organic solvents (toluene and o-xylene) are compared. The work was performed at the Division of Analytical Chemistry, Department of Chemistry, Moscow State University.
