Abstract

La présente invention concerne un matériau à fluorescence retardée activé thermiquement, un procédé de préparation correspondant et un dispositif à diode électroluminescente organique. La structure de formule générale du matériau à fluorescence retardée activé thermiquement est représentée dans la formule suivante I : (I), Dans laquelle R1 représente un groupe chimique d'un donneur d'électrons, et R2 représente un groupe chimique agissant en tant qu'accepteur d'électrons. Le matériau à fluorescence retardée activé thermiquement selon la présente invention a un taux de croisement intersystème inverse ultra-élevé et une efficacité d'émission de lumière élevée, et est un matériau TADF à lumière rouge ayant des caractéristiques TADF significatives. Le matériau à fluorescence retardée activé thermiquement peut être utilisé comme matériau de base d'une couche électroluminescente dans un dispositif à diode électroluminescente organique, ce qui permet d'améliorer de manière efficace l'efficacité luminescente du dispositif à diode électroluminescente organique, et le dispositif à diode électroluminescente organique basé sur le matériau à fluorescence retardée activé thermiquement selon la présente invention présente une efficacité de dispositif très élevée.
