EFFECT OF THE SUBSTITUTION PATTERN OF CHLOROANTHRAQUINONE ON THE FORMATION OF COMPLEX SALTS WITH SILVER

Silver and 1- or 2-chloroanthraquinone (1-CAQ or 2-CAQ) were sequentia lly evaporated at a temperature of 300 K at the thickness ratio t(Ag)/ t(CAQ) 0.15. The deposited films were analyzed by means of optical abs orption (IR, visible, near UV), Raman diffusion, X-ray diffraction, el ectron spin resonance, and Xray photo-electron spectroscopy. The compa rison of the results obtained with 2-CAQ and Ag/2-CAQ shows that no co mplex salt formation occurred between the Ag and the 2-CAQ superimpose d layers, Using 1-CAQ under similar conditions, however, the results a re in accordance with complex formation in superimposed layers with Ag , Interdiffusion and charge transfer (CT) are found to occur between s ilver and 1-CAQ, The degree of transfer is amplified by annealing.
