Reflectance spectra of organic matrices on the basis of photonic crystals formed of polystyrene microspheres with a particle size of 230 nm
Moscow University Chemistry Bulletin(2017)
摘要
The specular and diffuse reflectance spectra of organic matrices on the basis of photonic crystals formed of polystyrene microspheres with a particle size of 230 nm and polydimethylsiloxane layers, which are both applied on substrates made of quartz glass and acrylic plates, are recorded. Part of the organic matrix changes color from green to red-yellow 2 to 5 min after contact with a nonpolar solvent. The kinetics of structural changes occurring in the organic matrix under the influence of non-polar organic solvents, such as toluene, benzene, and n -hexane, is studied by diffusion reflectance spectroscopy. The equilibria in the organic matrix are achieved in 15–20 min.
