Abstract:
(EN) This electrochemical light emitting cell (10) comprises: a light emitting layer (12) which contains a polymer material that has a function of transporting electrons and holes, a light emitting material which emits light by receiving holes and electrons from the polymer material or by means of excitons formed of holes and electrons bound together on the polymer material, and an electrolyte; and electrodes (13, 14) which are respectively arranged on the surfaces of the light emitting layer (12). The light emitting material is a compound that has a pyrromethene skeleton. It is preferable that the light emitting layer (12) is colorless and transparent in the wavelength range of visible light in a state where no voltage is applied thereto.
(FR) La présente invention concerne une cellule électroluminescente électrochimique (10) comprenant : une couche électroluminescente (12) qui contient un matériau polymère à fonction de transport d'électrons et de trous, un matériau électroluminescent émettant de la lumière par réception de trous et d'électrons du matériau polymère ou au moyen d'excitons formés de trous et d'électrons liés les uns aux autres sur le matériau polymère, et un électrolyte ; et des électrodes (13, 14) qui sont respectivement disposées sur les surfaces de la couche électroluminescente (12). Le matériau électroluminescent est un composé à squelette pyrrométhène. Il est préférable que la couche électroluminescente (12) soit incolore et transparente dans la gamme de longueurs d'ondes de la lumière visible dans un état dans lequel aucune tension ne lui est appliquée.
(JA) 電気化学発光セル(10)は、電子及び正孔の輸送機能を有する高分子材料、該高分子材料から正孔及び電子を受け取って発光するか、又は該高分子材料上で正孔及び電子が結合して生成した励起子によって発光する発光材料、及び電解質を含む発光層(12)と、発光層(12)の各面に配された電極(13,14)とを有する。発光材料がピロメテン骨格を有する化合物である。発光層(12)は、電圧が印加されていない状態において、可視光の波長領域で無色透明であることが好適である。
