    Abstract: PURPOSE:To produce the title crystal which has a high strength isotropically and a network structure having covalent bonds multi-dimensionally by subjecting crystals obtained from diacetylenedicarboxylic acid, a polyvalent metal carbonate and/or a polyvalent metal acetate to solid-state polymerization. CONSTITUTION:0.1-100mmol/l of a solution of a diacetylenedicarboxylic acid of the given formula (wherein n is 0-20) is added to a solution of a polyvalent metal carbonate and/or a polyvalent metal acetate (e.g., copper acetate) in a molar ratio of the acid to the metal salt of 1:(1-2) to form a homogeneous solution or suspension, which is stirred to react them at room temperature to 100 deg.C or below, thereby producing diacetylenedicarboxylic acid metal salt crystals. The crystals are irradiated with ultraviolet light for several to 100 hours, or with tens of MRad to hundreds of MRad or gamma ray (e.g., cobalt 60) in a vacuum, or are heated at tens of degrees to 200 deg.C for tens of hours to hundreds of hours, or are subjected to several thousands to ten thousands of atmospheres for tens of minutes, thereby effecting the solid-state polymerization.

    Abstract: PURPOSE:To obtain the titled material useful as material for a light wavelength converting element, etc., stable at room temperature, readily providing large single crystal, comprising p-toluenesulfonic acid 1-methyl-4-[2-(4-hydroxyphenyl) vinyl[pyridinium. CONSTITUTION:An organic material for non-linear optical use comprising p- toluenesulfonic acid 1-methyl-4-[2-(4-hydroxyphenyl)vinyl] pyridinium shown by formula I and one comprising p-toluenesulfonyl acid 1-methyl-4-[2-(4-(N,N- dimethylamino)phenyl)] vinyl pyridinium shown by formula II. The compounds shown by formula I and formula II are synthesized by condensing 1,4- dimethylbipyridinium obtained from gamma-picoline and methyl iodide with 4- hydroxybenzaldehyde and 4-(N,N-dimethylamino)benzaldehyde through dehydration and reacting the reaction products with p-toluenesulfonic acid. Large single crystal is obtained by slow evaporation method, etc.

    Abstract: PURPOSE:To obtain the titled material capable of enlarging a SHG and having a stability at room temp. and enabling to easily growing a large monocrystal by selecting the 8 kinds of the compds. defined by the specific table from a specific ethynyl nitrobenzene derivative shown by the formula. CONSTITUTION:The titled material is composed of the ethynyl nitrobenzene derivative shown by the formula and comprises the 8 kinds of the compds. defined by the table. The prescribed derivative is prepared by reacting the corresponding halonitroiodobenzene derivative with the ethynyl derivative in a solvent and in the presence of a bispalladium II chloride catalyst. Thus, the titled material having the larger SHG than that of an urea by a few times and a stable at the room temp. and making an ease to grow a large monocrystal is obtd.

    Abstract: PROBLEM TO BE SOLVED: To form a polymerized film, which controls interaction between a substrate and a liquid crystal, on a cell substrate by incorporating a divinyl compound into the liquid crystal and photopolymerizing the divinyl compound on a cell substrate by being irradiated with light from a transparent substrate side. SOLUTION: A polymerized film is formed on a liquid crystal cell substrate in which a liquid crystal is encapsulated between two substrates at least one of which is a transparent substrate. For this purpose, a divinyl compound is incorporated into the liquid crystal and photopolymerized on the substrate by being irradiated with light from the side of the transparent substrate. The used divinyl compound has two vinyl groups in its molecule and is a low molecular weight compound having a molecular weight of 1,000 or lower, preferably 400 or lower. The lower limit of the molecular weight is normally about 250. The divinyl compound expressed by the formula is preferably used. In the formula, A denotes a linear molecule backbone part and R3-R8 each denotes hydrogen or a substituent. The linear molecule backbone part A includes a linear bivalent aliphatic group and the like.

    Abstract: PURPOSE:To obtain the subject crystal having isotropically high strength, by orienting a specific alkyldiamine perpendicularly on a surface of a substrate, depositing a diamine and a diacetylenedicarboxylic acid by vacuum evaporation and irradiating with ultraviolet ray, etc., to effect the solid-phase polymerization. CONSTITUTION:(A) An alkyldimine of formula I (n is 8-18) (e.g., diaminodecane) is deposited on (B) a substrate such as polished glass plate by vacuum evaporation at a heating temperature of the component A of 30-110 deg.C, a substrate temperature of -30-10 deg.C and a vacuum degree of 10 -10 Torr. Thereafter, (C) a diamine of formula II (R is alkyl, aryl, etc.) and (D) a diacetylenedicarboxylic acid of formula III (R is alkyl, aralkyl, etc.) are deposited on the surface by vacuum evaporation, polymerized and then irradiated with ultraviolet ray or ionizing radiation (e.g., gamma-ray of cobalt 60) to effect the solid-phase polymerization and obtain the objective crystal.
