Abstract: NEW MATERIAL:A compound of formula I [R is 2,5-or 3,5-bis(trifluoromethyl) phenyl, 4-aminophenyl or 2-pyridyl]. EXAMPLE:1-[2,5-bis(trifluoromethyl)phenyl]-5-(N-carbazolyl-1,3-pentadi yne. USE:Useful for functional materials such as nonlinear optical materials, photosensitive materials and polymeric semiconductor crystals. PREPARATION:An asymmetrical coupling is made between (A) an ethynylbenzene derivative of formula II and (B) N-(3-bromo-2-propynyl)carbazole of formula III into the objective compound of the formula I. The reaction is carried out in such a manner that an amine and copper chloride are added to a solution of the compound of the formula II followed by gradual addition of the compound of the formula III while stirring.

Abstract: PURPOSE:To easily obtain the subject material useful for electronic material, etc., by a solid-phase polymerization comprising the irradiation of a crystal of a specific tetraacetylene molecule with light or radiation or by a two-stage solid-phase polymerization comprising the thermal polymerization of the above crystal at a temperature below its melting point and the post-polymerization of the obtained polymer. CONSTITUTION:The objective conjugated polymer material consisting of a di(polydiacetylene) of formula IV can be produced either by irradiating a crystal of the molecule of a tetraacetylene of formula I [R and R' are CH3(CH2)x (x is 0-19) or group of formula II (y is 0-19; z is 1-9)] (e.g. 15,17,19,21- hexatriacontatetrayne) with light (e.g. ultraviolet light or visible light) or radiation (e.g. X-ray or gamma-ray) or by heating the crystal at a temperature below the melting point of the crystal to obtain a polymer of formula III (n is polymerization degree) and irradiating the polymer with light (e.g. ultraviolet light or visible light) or radiation (e.g. X-ray or gamma-ray) or heating the polymer.

Abstract: PROBLEM TO BE SOLVED: To provide a thermosensitive recording medium which has full-color recording and rewritable characteristics made compatible with each other and an image forming method. SOLUTION: This rewritable color image recording medium provided with a thermosensitive layer containing a cholesteric liquid crystal compound which has =35 deg.C glass transition temperature is provided between two substrates, at least one of which is transparent. An image is formed by varying the temperature of the rewritable color image recording medium from 1st temperature to 2nd temperature (the cholesteric liquid crystal compound forms a cholesteric liquid phase at least one of the 1st temperature and 2nd temperature) according to the desired image, and then fixed by rapidly cooling the recording medium so that the thermosensitive layer is cooled to the glass transition temperature or below.

Abstract: PURPOSE:To increase the transmissivity of blue light and a nonlinear optical constant by providing an org. material composed of specific p-toluene sulfonic acid 1-methyl-4-(2-(4-cyanophenyl)vinyl)pyridinium. CONSTITUTION:This org. material for nonlinear optics consists of the p-toluene sulfonic acid 1-methyl-4-(2-(4-cyanophenyl)vinyl)pyridinium expressed by formula I. The p-toluene sulfonic acid 1-methyl-4-(2-(4-cyanophenyl)vinyl)pyridinium is a single crystal without having a symmetrical center and exhibits the SHG activity of several times the SHG activity of urea. In addition, the light absorption end in the crystal is as shorter in wavelength as about
