  The invention relates primarily to a retardation film and a process for producing the retardation film, wherein a layer formed of a mixture of a photosensitive polymer and a low molecular weight compound is irradiated with linear polarized ultraviolet ray, ultraviolet ray including a perfectly polarized light component and a non-polarized light component, or a non-polarized ultraviolet ray to orient molecules thereby developing a retardation and the direction of the optical axis arbitrarily in the layer formed of a mixure.

  本发明主要涉及一种缓凝薄膜和生产该缓凝薄膜的工艺，其中用线性偏振紫外线、包括完全偏振光分量和非偏振光分量的紫外线或非偏振紫外线照射由光敏聚合物和低分子量化合物混合物形成的层，使分子定向，从而在由混合物形成的层中任意形成缓凝和光轴方向。
• Surface Properties and Aggregates in the Mixed Systems of Bolaamphiphiles and Their Oppositely Charged Conventional Surfactants

  Two transition points were observed in the surface tension curves of the mixed systems of cationic bolaamphiphile BPHTAB (biphenyl-4,4'-bis(oxyhexamethylenetrimethylammonium bromide)) and its oppositely charged conventional surfactants. Transmission electron microscopy, dynamic light scattering, and isothermal fitration m icrocalori metric experiments demonstrated that spherical vesicles or elongated aggregates formed at the lower surfactant concentration than the corresponding critical micelle concentration (cmc), which led to the existence of two transition points in surface tension curves. Addition of 10% formamide into the mixed system broke the vesicles and elongated aggregates and made the first breaking point disappear. The biphenyl group in the BPHTAB molecule and the appropriate attractive interaction between the cationic and anionic headgroups of the surfactants had a great influence on the ability of vesicle formation and determined whether the two transition points would exist in the surface tension curve.

• Molecular Organization of Preorganized S-Shaped Oligomers in the Liquid Crystalline Phases

  We prepared a homologous series of S-shaped oligomers, 4,4'-bis(omega-(2-(omega-(4-(cyanophenyl)phenyloxy)alkyloxy)phenyloxy)alkyloxy)biphenyl [I-(m,n)], and investigated effects of the spacer length on the phase transition behavior. I-(7,7), I-(8,8), I-(9,9) and I-(7,9) showed nematic (N) and smectic A (SmA) phases, whereas I-(6,6) and I-(6,9) showed only an N phase. The melting behavior was found to depend on the parity of the spacer (m). The liquid-crystalline phases of I-(8,8) and I-(6,9) are monotropic, however, those of I-(9,9) and I-(7,9) are enantiotropic. X-ray diffraction measurements of I-(7,7), I-(8,8) and I-(7,9) indicate that the S-shaped oligomers exist as a close-packed structure in the monolayer SmA phase.
