  experimentally observed optical behaviour, time-dependent density functional theory (TDDFT) calculations have been performed. The potential use of single crystals of 1 has been tested in optical waveguide applications. The present work demonstrates the significance of soft interaction guided packing in the origin of both mechanical and optical properties of organic single crystals.

  近年来，具有机械柔软性和光学性质的单芳族化合物单晶引起了极大的科学兴趣，但它们非常稀缺。在本文中，1,3-二氨基-2,4,5,6-四溴苯（化合物1）的单晶显示在机械变形时表现出优异且出乎意料的弹性行为。的晶体结构分析1示出了负责对这样的柔性行为的分子间相互作用（BR⋯溴，N⋯Br和N-H⋯溴）。此外，发现1晶体的弹性模量约为 12 GPa，这是通过可弯曲主 (100) 面上的纳米压痕实验确定的。此外，有趣的是，化合物1还发现尽管没有任何显着的扩展共轭，但在固体和溶液状态下都在较长波长区域（橙色发射）中表现出光学特性。为了使实验观察到的光学行为合理化，已经进行了时间相关密度泛函理论 (TDDFT) 计算。已在光波导应用中测试了1单晶的潜在用途。目前的工作证明了软相互作用引导堆积在有机单晶机械和光学性质起源中的重要性。

  An anti-bacterial polymer of the present invention consists of a vapor deposition-polymerization reaction product of a diaminobenzoic acid monomer or halogen atom-containing diamine monomer and a monomer reactive with these monomers. The anti-bacterial polymer can be prepared by a method, which comprises the step of subjecting a gas obtained by evaporating a diaminobenzoic acid monomer or halogen atom-containing diamine monomer and a gas obtained by evaporating a monomer reactive with these monomers to vapor deposition-polymerization, in a vacuum, to thus form an anti-bacterial polymer. The method permits the formation of a film having a desired thickness even on the surface having a complicated shape such as the surface of, for instance, a heat exchanger.

  A method for producing a fluorine-containing polyimide film excelling in heat resistance, resistance to chemicals, water repellency, dielectric properties, electrical properties, and optical properties and a spin coater suitable for the method are to be provided. A method for the production of a fluorine-containing polyimide film which comprises forming a coating film of a fluorine-containing polyimide precursor in an atmosphere having a relative humidity thereof adjusted to a level of not more than 50 RH% and then subjecting the fluorine-containing polyimide precursor to heat treatment thereby forming a fluorine-containing polyimide film is provided. By adjusting the relative humidity in accordance with this method, the fluorine-containing polyimide precursor can be prevented from being decomposed by the absorption of moisture. This measure effectively prevents the fluorine-containing polyimide film from forming piriform spots and scratches.
