Production and spectroscopic study of low-temperature silver complexes with mesogenic cyanobiphenyl derivatives

Metal-containing liquid-crystalline systems were obtained by co-condensation of metallic silver vapour with evaporated liquid-crystalline 4-pentyl-4′-cyanobiphenyl (5CB) under conditions of molecular beams. A comprehensive infra-red and ultraviolet-visible spectroscopic study of Ag-5CB film samples...

Summary:Metal-containing liquid-crystalline systems were obtained by co-condensation of metallic silver vapour with evaporated liquid-crystalline 4-pentyl-4′-cyanobiphenyl (5CB) under conditions of molecular beams. A comprehensive infra-red and ultraviolet-visible spectroscopic study of Ag-5CB film samples of different component ratios at 80 K shows the existence of Ag-5CB complexes owing to interactions of Ag with the π-electrons of the CN bond of cyanobiphenyl molecules.
