Abstract | Provided is a light-emitting element having low drive voltage. A light-emitting element having an anode, a cathode, and a first organic layer and second organic layer provided between the anode and the cathode, the first organic layer containing the light-emitting material represented in formula (T), and the second organic layer containing a crosslinked body of a polymer compound including a crosslinking constituent unit. (In the formula: nT1 represents an integer from 0 to 5; nT2 represents an integer from 1 to 10; ArT1 represents a unicyclic or condensed cyclic monovalent heterocyclic group including, as a ring-constituent atom, a nitrogen atom without a double bond, and not including, as an ring-constituent atom, a nitrogen atom having a double bond; LT1 represents an alkylene group, an arylene group, or the like; and ArT2 represents a unicyclic or condensed cyclic heterocyclic group including, as a ring-constituent atom, a nitrogen atom having a double bond.)
L'invention concerne un élément électroluminescent ayant une faible tension d'attaque. Un élément électroluminescent comprend une anode, une cathode et une première couche organique et une seconde couche organique disposée entre l'anode et la cathode, la première couche organique contenant le matériau électroluminescent représenté par la formule (T), et la seconde couche organique contenant un corps réticulé d'un composé polymère comprenant une unité constitutive de réticulation. (Dans la formule : nT1 représente un nombre entier de 0 à 5; nT2 représente un nombre entier de 1 à 10; ArT1 représente un groupe hétérocyclique monovalent cyclique uni-cyclique ou condensé comprenant, en tant qu'atome constitutif de cycle, un atome d'azote sans double liaison, et ne comprenant pas, en tant qu'atome constitutif de cycle, un atome d'azote ayant une double liaison; LT1 représente un groupe alkylène, un groupe arylène, ou similaire; et ArT2 représente un groupe hétérocyclique cyclique unicyclique ou condensé comprenant, en tant qu'atome constitutif de cycle, un atome d'azote ayant une double liaison.)
駆動電圧が低い発光素子を提供する。 陽極と、陰極と、陽極及び陰極の間に設けられた第1の有機層及び第2の有機層とを有し、第1の有機層が、式(T)で表される発光材料を含有する層であり、第2の有機層が、架橋構成単位を含む高分子化合物の架橋体を含有する層である、発光素子。[式中、nT1は、0~5の整数を表す。nT2は、1~10の整数を表す。ArT1は、環構成原子として二重結合を有さない窒素原子を含み、且つ、環構成原子として二重結合を有する窒素原子を含まない、単環又は縮合環の1価の複素環基を表す。LT1は、アルキレン基、アリーレン基等を表す。ArT2は、環構成原子として二重結合を有する窒素原子を含む、単環又は縮合環の複素環基を表す。] |
