    摘要： Provided are a fluorescence-emitting material which improves luminous efficiency of an organic light-emitting element such as an organic EL element or an organic PL element and an organic light-emitting element using the fluorescence-emitting material. The fluorescence-emitting material includes a compound having an indolocarbazole skeleton represented by the following general formula (1). The organic light-emitting element includes an organic EL element including: a substrate; an anode; a cathode; and a light-emitting layer, the anode and the cathode being laminated on the substrate and the light-emitting layer being sandwiched between the anode and the cathode, in which the light-emitting layer includes: the organic light-emitting material; and as a host material, an organic compound having excited triplet energy higher than that of the organic light-emitting material. In the general formula (1): a ring A represents an aromatic ring represented by the formula (1a) to be fused with an adjacent ring; a ring B represents a heterocycle represented by the formula (lb) to be fused with an adjacent ring; Ar represents an aromatic hydrocarbon group or an aromatic heterocyclic group; R's each represent hydrogen or a monovalent substituent; and n represents an integer of 1 to 4.

    摘要： An organic EL material according to the present invention includes a compound represented by the general formula (I). In the formula (I), R 1 and R 2 are each independently a hydrogen atom or any substituent, and are preferably each independently a substituent selected from the group consisting of a hydrogen atom, a cyano group, a halogen-substituted alkyl group, a halogen, a pyridyl group optionally having a substituent, and an electron-donating aromatic group. A is a substituent in which at least one heteroaryl group optionally having a substituent, or at least one aryl amino group optionally having a substituent is bonded to a carbon atom at the 4-position of the pyridine ring directly or through other aromatic group.

    摘要： The present invention provides a thermoelectric conversion material having a low thermal conductivity and having an improved figure of merit, and a method for producing it. The thermoelectric conversion material has, as formed on a substrate having a nano-level microporous nanostructure, a thermoelectric semiconductor layer prepared by forming a thermoelectric semiconductor material into a film, wherein the substrate is a block copolymer substrate formed of a block copolymer that comprises a polymethyl methacrylate unit and a polyhedral oligomeric silsesquioxane-containing polymethacrylate unit, and the thermoelectric semiconductor material is a p-type bismuth telluride or an n-type bismuth telluride. The production method comprises a substrate formation step of forming the nanostructure-having block copolymer substrate, and a film formation step of forming a p-type bismuth telluride or an n-type bismuth telluride into a film to thereby provide a thermoelectric semiconductor layer.
