Thin films of vacuum sublimated [4-(phenylamino) phenyl]-1,4-benzenediamine were elaborated by changing deposition parameters. The influence of these parameters on the structural organization of the films is studied by several techniques, such as X-ray diffraction, Scanning Electron Microscopy, UV-vis-NIR optical and polarized infrared absorption. All these results are discussed by comparison to a similar previous study of N,N'-diphenyl-1,4-phenylenediamine and reveal that, using convenient deposition parameters, one can obtain textured films, in which the organic molecules stand almost perpendicular to the substrate. Preliminary doping experiment of these films is presented in the aim of potential use in sensor devices. (C) 2003 Elsevier B.V. All rights reserved.
