Title (EN) ORGANIC ELECTROLUMINESCENT ELEMENT
(FR) ÉLÉMENT ÉLECTROLUMINESCENT ORGANIQUE
(JA) 有機電界発光素子
Abstract: front page image
(EN)This organic electroluminescent element is provided with a positive electrode (10), a negative electrode (20), and a light-emitting layer (30), which is liquid at room temperature, disposed between these electrodes. The light-emitting layer contains a coordinating non-ionic material, such as that represented by formula (7), and a coordinating substituent with a polyether structure etc., such as TeEGCz, TEGCz, TPGCz, EOECz, or DEGCz, and further contains a material having carrier-transporting ability and a light-emitting ability. Thus, organic electroluminescent elements, which are provided with a liquid light-emitting layer that can maintain a liquid state both when being driven and when not being driven, and which have good light emission lifespan characteristics, can be provided.
(FR)L'invention porte sur un élément électroluminescent organique qui est pourvu d'une électrode positive (10), d'une électrode négative (20) et d'une couche électroluminescente (30), qui est liquide à température ambiante et qui est disposée entre ces électrodes. La couche électroluminescente contient un matériau non ionique de coordination, tel que représenté par la formule (7), et un substituant de coordination à structure polyéther, etc., tel que TeEGCz, TEGCz, TPGCz, EOECz ou DEGCz, ainsi qu'un matériau ayant une aptitude au transport de porteurs et une aptitude à émettre de la lumière. Ainsi, des éléments électroluminescents organiques, qui sont pourvus d'une couche électroluminescente liquide qui peut conserver un état liquide à la fois lorsqu'elle est excitée et lorsqu'elle n'est pas excitée, et qui ont de bonnes caractéristiques de durabilité de l'émission de lumière, peuvent être utilisés.
(JA) 陽極10と、陰極20と、これら各極間に介在する、常温で液体の発光層30とを備え、発光層が、例えば、式(7)で示されるような、配位性非イオン性材料や、TeEGCz、TEGCz、TPGCz、EOECz、DEGCz等のポリエーテル構造等の配位性置換基を含み、キャリア輸送能および発光能を有する材料を含む有機電界発光素子。これにより、液体の発光層を備え、駆動時および非駆動時ともに発光層が液状を維持し得るとともに、発光寿命特性の良好な有機EL素子を提供できる。
