Abstract

Two methods for preparing highly oriented crystalline polyimide filmscomprised of oligo-p-phenylene sulfide [-(C6H5S)n-1-C6H4-:n = 3,4,5...] monomers have been developed, which show novel photoconductivity. The first method is using modified terminals of the polymer chains for carboxylic anhydrides as crystallization nuclei in order to enhance the crystallization of the (oligo phenylene sulfide)-polyimides (OPS-PIs). The second uses a Langmuir-Blodgett polyimide underlayer to prepareoriented OPS-PI films parallel to the substrate, extending up to several microns. The Langmuir-Blodgett polyimide underlayer introduces an oriented epitaxial crystallization of the OPS-PIs. Anisotropic photocurrent measurements on these films revealed an anisotropic photoconduction mechanism in which carriers were transported perpendicular to the polymer chain axis.
