発明の名称 (英語) ORGANIC OPTICAL MATERIAL NEW
発明の概要(英語) Provided is a new donor-acceptor compound that emits light even in a solid state. The present invention provides an organic optical material in which (1) a conjugated molecule that has (a) at least one electron-donating site, (b) at least one electron-accepting site, and (c) at least one conjugated site in each molecule, and (2) a proton-donating or electron-pair-accepting compound form, at the electron-accepting site, a complex that exhibits a non-covalent interaction. The organic optical material is characterized in that the complex is solid at room temperature, and exhibits the property of emitting light having a maximum fluorescence wavelength at which there is a Stokes shift of at least 5% of the value of the maximum absorption wavelength from the maximum absorption wavelength towards the long wavelength side.
従来技術、競合技術の概要(英語) BACKGROUND ART
Light-emitting organic compound, biological labeling materials, the organic electronics material, a chemical sensor, and a wide range of fields such as organic lasers have been used, has been actively under research and development of new light-emitting material are performed. Especially X-ray or ultraviolet, or visible light fluorescence emitted by the organic compound is an organic fluorescent paints and the like in addition to the applications described above can also be used. However, generally used as a light-emitting organic material is strong and the planarity of the molecule is large and a high molecular weight, the molecular solution to reduce interference with the amount of contact between those light-emitting diodes, such as a crystalline state in a solid state is in the vicinity of the energy of the electromagnetic waves to be attenuated under the influence of a planar molecule, light emission efficiency is significantly reduced in many cases. Light-emitting organic material is, on the application, in some cases be used in the solid state, solution as well as the intense light-emission in the solid state as being important issues in the development of the material.
Donor-acceptor-type compound has been reported a number, a variety of characteristics have been known. Patent Document 1 is, not only the solid solution having a high luminous efficiency even in a state where the nitrogen-containing aromatic ring is disclosed in the fluorescence-emitting compound. Non-Patent Document 1 is, so-called compound type donor-acceptor both conjugate with respect to the compounds, hydrochloric acid, trifluoroacetic acid, boron tribromide to act as an activating agent that can control the fluorescent wavelength is described. Is the non-patent document 2, a dimethylamino group and pyridine ring compounds and boron-containing compound to the action of the various analyses performed, a nitrogen atom and the boron atom of the pyridine ring and acting on the dipole moment is found to be increased, the influence on the fluorescence wavelength is not disclosed.
