Fiber-oriented film was prepared by electrospinning method using polyvinyl alcohol with stylbazol quaternized group (PVA-SbQ), and the formation behavior of polyiodine complex in fibers was investigated. From the UV-vis spectra and the Raman spectra, it was revealed that PVA-I � � was formed in the fiber orientated film after staining. It is presumed that in the fiber oriented film, the iodine complexes are aligned in one direction. It is considered that the polyiodine complex is inductively arranged with respect to the orientation of fibers, which contributes to the development of dichroism.

Oxime derivatives, having a N-O bond in the molecule structure, are excellent photo reactive compounds.Oxime type photoacid generaters with adamantyl and perfluoroalkylsulfonyloxy groups and without aromatic groups were prepared, and their absorption spectra and thermal properties were measured. The compounds designed with photoacid generator in deep ultraviolet (DUV) region have good transparency in the region. The thermal stability of these PAGs depended on the chain length of acid precursor groups. The quantum yields of acid generation were substantially high. These aliphatic oxime sulfonates can be expected to be PAGs in DUV.
