Utilizing the low speed bar-coating method which is a kind of solution process, uniaxially oriented thin films of organic semiconductor, the pentyl-substituted phthalocyanines (C5PcH₂), have been fabricated and the molecular orientation and crystal structure of the films have been investigated by the grazing incidence wide-angle X-ray scattering (GIWAXS) technique. The crystal structure of the film fabricated by spin-coating has corresponded to the metastable phase of C5PcH₂, while that fabricated by bar-coating has corresponded to the stabilized phase. The molecular orientation and crystal structure of film depending on the film fabricating condition have been discussed.
