Abstract[English]
LE) in the excited triplet state of the cyclic tetradentate platinum(II) complex, thereby achieving a low shoulder peak, improved emission color purity of material molecules, and enhanced stability of materials. The materials provided by the present invention all have good chemical stability and thermal stability, thereby facilitating the preparation of evaporation-type OLED devices. The organic electroluminescent device manufactured by using the complex of the present invention as a light-emitting layer has a significant improvement in both the current efficiency and service life, and can also reduce the turn-on voltage.[French]
LE) dans l'état triplet excité du complexe de platine (II) tétradentate cyclique, ce qui permet d'obtenir un faible pic d'épaulement, une pureté de couleur d'émission améliorée de molécules du matériau, et une stabilité améliorée des matériaux. Les matériaux selon la présente invention présentent tous une bonne stabilité chimique et une bonne stabilité thermique, ce qui facilite la préparation de dispositifs DELO de type à évaporation. Le dispositif électroluminescent organique fabriqué à l'aide du complexe selon la présente invention en tant que couche électroluminescente présente une amélioration significative à la fois de l'efficacité actuelle et de la durée de vie, et peut également réduire la tension d'activation.[Chinese]
