Uniaxially oriented thin films of a thermally stable phthalocyanine, tetra-tert-butyl phthalocyanine (t-BuPcH₂), were fabricated by bar-coating method. The optical property and molecular packing structure of the t-BuPcH₂ in the thin film were investigated. The thin film exhibited high absorption dichroic ratio of about 50 at the peak wavelength. The molecular packing structure was determined from XRD measurement; the column axis of t-BuPcH₂ molecule was parallel to the bar-sweep direction, and the molecular plane was perpendicular to the column axis. In addition, X-ray rocking curve indicated high crystallinity of the thin film.
