Abstract: A novel polyimide resin is formed by imidizing a diamine component including an amide group-containing siloxane diamine compound represented by the following formula (1) and an acid dianhydride component including an aromatic acid dianhydride such as 3,3?,4,4?-diphenylsulfone tetracarboxylic dianhydride. This novel polyimide resin utilizes a novel polyimide resin into which a reaction group capable of reacting with a crosslinking agent to form a crosslinking point is pre-introduced before imidization. The novel polyimide resin can confer a comparatively low elastic modulus and heat resistance to a dry film or a photosensitive cover film formed from a photosensitive polyimide resin composition containing the novel polyimide resin. In the formula (1), R1 and R2 are each independently an optionally-substituted alkylene group, m denotes an integer of 1 to 30, and n denotes an integer of 0 to 20.

Abstract: The present invention relates to an electric transfer light emitting polymer that emits light by applying an electric field thereto. Chlorine (Cl) and the sum total (?M) of metal elements included in the polymer satisfies a relation of a below-described formula 1. ?M<Cl ??(1) (In this case, ?M designates the sum total of metal elements composed of one kind or a plurality of kinds between alkali metal elements, alkali earth metal elements, elements in the third period showing no anionic characteristics, elements in the fourth period showing no anionic characteristics and elements in the fifth period showing no anionic characteristics.

Abstract: A novel electroluminescence polymer offers stable EL characteristics: it forms little aggregates and is less susceptible to morphological changes during and after film formation. The EL polymer comprises a binaphthyl derivative structural unit represented by the following formula (1a) and an aryl structural unit represented by the following formula (1b): wherein Ar is an aryl structural unit that can form an electroluminescent ?-conjugated polymer; R1, R2, R3, and R4 are each independently a different functional group; the double bonds of the binaphthyl structural unit indicated by dashed lines and solid lines are each an unsaturated double bond or a saturated single bond; m and p are each independently an integer of 0 to 2; n and o are each independently an integer of 0 to 8; x is the molar fraction of the binaphthyl derivative structural units; and y is the molar fraction of the aryl structural units.

Abstract: An electroluminescent polymer which has repeating units represented by formula (1) is obtained by polymerizing a bisfluorenylsilane compound which has specified substituent groups. In spite of the fact that this electroluminescent polymer is a ?-? conjugated type fluorene polymer, the deterioration in the color purity of EL caused by excimer formation is suppressed, so that the color purity of blue emitted light in particular is extremely high. This electroluminescent polymer is extremely useful as a light-emitting material in organic electroluminescent elements.
