    Abstract: PURPOSE:To enable measurement of the thickness of a thin film in a noncontact manner with a thin film sample and handily while the thin film is being made by irradiating an organic thin film with X-rays at an angle of incidence to determine a maximal value of an intensity of X-rays at a position of an angle of reflection. CONSTITUTION:An apparatus herein used is such that is used when a normal reflection X-ray diffraction is measured and it is provided with a goniometer mechanism in which an X-ray detector is positioned in a direction of reflection angle theta, namely, in a direction of angle 2theta to incidence of X-rays when an angle of a plane of a thin film is theta with respect to a direction of incidence of X-rays. In an apparatus of such a type, theta is swept continuously to perform a recording in a relationship between an angle 2theta of the detector and a detection intensity of X rays. At this point, as some peaks are noted continuously, values of 2theta of this series of peaks are read out. Then, a film thickness is calculated using an expression II derived from a Bragg's reflection formula (formula I). In this manner, values of film thicknesses obtained for the peaks are averaged or averaged being weighted statistically to determine a film thickness.

    Abstract: NEW MATERIAL:A compound of formula I [one of R1 and R2 is nitro and the other is H; either one of R1'-R3' is -NHCO-(CH2)n-CO2H (n is 6-18) and the others are H]. EXAMPLE:2-(4-(3-Nitrophenyl)-1,3-butadiynyl)phenylcarbamoylnonadecanoic acid.

    Abstract: PURPOSE:To improve stability with age by mixing a high-polymer electrolyte soln. and an ionic dye soln. to form the composite of the high-polymer electrolyte and the ionic dye. CONSTITUTION:The composite of the high-polymer electrolyte and the ionic dye is formed by mixing the high-polymer electrolyte soln. and the ionic dye soln. The composite of the high-polymer electrolyte and the ionic dye is bonded by the electrostatic interaction between the residual ion groups possessed by the same and, therefore, the composite contains the ionic dye at the high concn. from several ten to hundred mol% per residual ionic group of the high-polymer electrolyte. The composite can be easily made into a cast film by dissolving the same into water, polar solvent such as alcohol, or a solvent contg. inorg. ions such as sodium chloride or acid and alkalis such as hydrochloric acid and sodium hydroxide therein. This cast film is optically uniform and transparent and the dye molecules therein are bonded to each other by the electrostatic interaction. Isotropy is obtd. in this way and the stability with age is improved.
