C-NITROSO COMPOUNDS AS NOVEL PROMISING SUBSTANCES FOR THE DEPOSITION OF LANGMUIR-BLODGETT-FILMS

C-nitroso compounds and their complexes with transition metals have ne ver been used before in Langmuir experiments. Some isotherms have been registered for several C-nitroso derivatives and for two metal comple xes with Pd(II) and Rh(I) thin films were deposited by the standard ve rtical dipping method, UV-Vis spectroscopy has been performed in order to analyse the absorption bands of the deposited films. Measurements of the dependence of the conductivity were carried out between 300 and 450 K. All samples display an activated conductivity at high temperat ure and related activation energies were determined. A decrease of the activation energy is reported for the palladium complex thin films in to a flux of air and ppm NO2.
