Abstract: PROBLEM TO BE SOLVED: To improve the luminous intensity by applying a mechanical stress to a fullerene provided with such a feature that it emits white light when irradiated with argon laser beams or when an electric current flows therethrough. SOLUTION: A fullerene C60 film with a thickness of 1-10μm is formed by vacuum deposition on a base plate comprising, e.g. fused silica, a slide glass, Pyrex, a silicon wafer, an alkali halide, a plastic, or a ceramic. A mechanical stress is applied with a sharp edge of, e.g. a knife, a needle or a glass cutter to the formed C60 film to produce scratches on the surface thereof. The C60 film with scratches is irradiated with argon laser beams having a wavelength of 514.5nm to 30mW or allowed to pass an electric current therethrough to cause the emission of white light having a vary wide wavelength distribution (600-4,500nm) over a visible light to infrared region, with a light intensity peak in a wavelength region from 1,500 to 2,000nm.

Abstract: PURPOSE:To obtain a diacetylene derivative which has an S atom directly bonded to a C atom in the triple bond and shows a large electronic effect and solid-phase polymerizability, thus is useful as a functional material such as a nonlinear optical material, a photosensitive material and a polymer semiconductor crystal. CONSTITUTION:The compound of formula I [Ar , Ar are (substituted) phenyl; n is 1-8], for example, 8-(4-bromophenyl)thio-5,7-octadiynyl phenylcarbamate. The compound of formula I is prepared by protecting the terminal hydroxy group in omega-hydroxy-1,3-alkadiyne of formula II, introducing an arylthio group into the 1-position of the protected omega-hydroxy-1,3-alkadiyne, deprotecting the product of the diacetylene derivative of formula III and allowing the deprotected hydroxyl to react with an aryl isocyanate to effect introduction of a urethane group on the chain terminal.

Abstract: PROBLEM TO BE SOLVED: To obtain a light source capable of providing the polarized luminescence by forming a first polysilane film on a transparent anode plate by using solvent insoluble polysilane, forming a second polysilane film on the first polysilane film by using a solvent soluble polysilane, and mounting a cathode plate on the second polysilane film. SOLUTION: A polarized luminescence EL element comprises a first polysilane orientation film 2 oriented by a mechanical deposition method and formed on a transparent anode plate 1, a second polysilane orientation film 3 orientated by an epitaxial growing and formed on the first polysilane orientation film 2, and further a cathode plate 4 formed on the second polysilane orientation film 3. By mounting a hole blocking layer 5 between the second polysilane orientation film 3 and the cathode plate 4, the flowing of positive charge to the cathode can be prevented, and the characteristic of the EL element can be further stabilized. By combining two kinds of polysilane orientation films, an uniform orientation film is formed in the element, and the minimized EL element of high efficiency can be provided.

Abstract: PURPOSE:To obtain a photovoltaic element in which phthalocyanine having excellent stability is used as a dispersion medium by heat treating a phthalocyanine resin dispersion type photovoltaic element using a cadmium sulfide for a defect electrode to provide excellent photoelectric energy conversion efficiency. CONSTITUTION:A film made of polyvinylidene compound which contains phthalocyanine in a dispersive state is used as an optically active layer, and heat treated for an element interposed between the cadmium sulfide defect electrode and an ohmic electrode. An X-type nonmetal phthalocyanine resin dispersive film is formed on a cadmium sulfide layer (or the ohmic electrode) by heat treating, and formed on a photovoltaic element composed by forming the ohmic electrode (or the cadmium sulfide layer) or an element formed with an x-type nonmetal phthalocyanine resin dispersive film on the cadmium sulfide layer. In the latter case, after heat treating, the ohmic electrode is formed to construct a photovoltaic element.

Abstract: PURPOSE:To provide a photoelectric cell having a high conversion efficiency, by interposing a beta crystal phase quinacridon as an organic thin film material between two different electrodes and thereby forming a sandwitch structure. CONSTITUTION:A photoelectric cell is obtained in a manner that a beta crystal phase quinacridon evaporation film is formed by heat treating a quinacridon thin film which has been obtained by vacuum depositing on an electrode in an electric furnace or, alternatively, vacuum depositing quinacridon on a heated electrode, and another electrode is joined thereto. In the heat treating process of the quinacridon evaporation film, the heat treating temperature is set at 200-300 deg.C, preferably at 230-270 deg.C. The quinacridon evaporation film is thereby caused to make transition from the violet-red alpha crystal phase to the beta crystal phase. In the other process for obtaining the crystal phase quinacridon evaporation film, namely substrate heating process, quinacridon is vapor deposited on the heated substrate, whose temperature is set at 100-300 deg.C, and preferably at 130-180 deg.C.

Abstract: PROBLEM TO BE SOLVED: To obtain a luminescent material that can give a fullerene-dispersed film having an enhanced luminous intensity by dispersing a fullerene in a polymer having alkyl groups as side chains. SOLUTION: The main chain that forms the polymer skeleton of the polymer having alkyl groups as side chains may be a carbon chain or a carbon chain that has hetero atoms such as Si and O. A typical example is a carbon chain or a chain having Si. The alkyl groups as side chains are desirably of 1-8 carbons. Side chains other than the alkyl groups are exemplified by aromatic hydrocarbon groups, ether groups, ester groups, cyano groups, carboxy groups, and amido groups. The polymer used is exemplified by polymethyl methacrylate or poly(methylphenylsilane). The fullerene used is 60C fullerene, 70C fullerene, or an analogue thereof. Although the fullerene may be dispersed in a suitable amount, the amount of the dispersed fullerene is suitably 0.3-30 wt.% based on the polymer. The luminescent material has a shape typified by a film.
