Abstract[English]
LE) is increased 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 provided materials all have good chemical stability and thermal stability, thereby facilitating the preparation of evaporation-type OLED devices. The organic electroluminescent device manufactured using the above-described compound as the light-emitting layer has a significant improvement in both the blue light index (BI) and service life, and can also reduce the turn-on voltage.[French]
LE) est augmentée 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 des molécules du matériau, et une stabilité améliorée des matériaux. Les matériaux selon l'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 composé décrit ci-dessus en tant que couche électroluminescente présente une amélioration significative à la fois de l'indice de lumière bleue (BI) et de la durée de vie, et peut également réduire la tension d'activation.[Chinese]
