Abstract :
A novel approach for controlling the adsorption-desorption processes on the surface of organic molecular crystals as sensitive layers for cross-selective sensor array are investigated. The approach demonstrated for QCM sensors covered by thin films of various phthalocyanines (CuPc, PbPc and H2Pc) illuminated in the visible and infrared region. The possible ways of utilizing of the proposed approach for the analysis of multicomponent chemical mixtures are discussed.
