Abstract
(EN)
The present invention provides a composite material for a light-emitting element including a high molecular compound having an arylamine skeleton and an inorganic compound showing an electron accepting property to the high molecular compound. The absorption spectrum of the composite material is different from absorption spectra of the high molecular compound and the inorganic compound which each form the composite material. In other words, a composite material having an absorption peak in a wavelength which is seen in the absorption spectra of neither the high molecular compound nor the inorganic compound forming the composite material is superior in carrier transporting and injecting properties and a favorable material. In addition, the composite material can be formed by a wet method such as a sol-gel method, it can be apply to the increase of substrate size easily in a manufacturing process and advantageous industrially.

La présente invention portera matériaux composites pour éléments émetteurs de lumière comprenant un composé de masse moléculaire élevée possédant un squelette d'arylamine et un composé inorganique ayant la propriété d'accepteur d'électrons vis à vis du composé de masse moléculaire élevée. Le spectre d'absorption du matériau composite est différent des spectres d'absorption du composé de masse moléculaire élevée et du composé inorganique qui forment chacun le matériau composite. En d'autres termes, un matériau composite, ayant une pointe d'absorption dans une longueur d'onde observée dans les spectres d'absorption d'un composé quelconque de masse moléculaire élevée ou d'un composé inorganique quelconque formant le matériau composite, présente de meilleures propriétés de transport et d'injection de l'excipient et s'avère être un matériau favorable. De plus, le matériau composite peut être obtenu par un procédé par voie humide, tel qu'un procédé sol-gel, peut être appliqué pour augmenter la taille du substrat facilement dans un procédé de fabrication industriel avantageux.
