Abstract:
(EN) Disclosed is a thermal excitation delay fluorescent material capable of improving luminous efficiency and stability, a polymer, a mixture, a composition, and an organic electronic device comprising same.This thermal excitation delay fluorescent material comprises a conjugated unit comprising at least two aromatic rings or heteroaromatic rings, so as to achieve thermal excitation delay fluorescence (TADF) luminescent characteristics. This thermal excitation delay fluorescent material can be used as a TADF luminescent material to improve the luminous efficiency and stability of the electroluminescent device containing such a thermal excitation delay fluorescent material by cooperating with a suitable host material, thereby providing a solution of the luminescent device which has low manufacturing cost, a high efficiency, a long life, and being low in roll-off.
(FR) La présente invention concerne un matériau à fluorescence retardée par excitation thermique apte à améliorer l'efficacité et la stabilité à la lumière, un polymère, un mélange, une composition, et un dispositif électronique organique le comprenant. Ce matériau à fluorescence retardée par excitation thermique comprend un motif conjugué comprenant au moins deux cycles aromatiques ou cycles hétéroaromatiques, afin d'atteindre des caractéristiques de luminescence de type fluorescence retardée par excitation thermique (TADF). Ce matériau à fluorescence retardée par excitation thermique peut être utilisé comme matériau luminescent TADF pour améliorer l'efficacité lumineuse et la stabilité du dispositif électroluminescent contenant un tel matériau à fluorescence retardée par excitation thermique en coopérant avec un matériau hôte approprié, fournissant ainsi une solution de dispositif luminescent qui présente de faible coût de fabrication, une efficacité élevée, une longue durée de vie, et un affaiblissement faible.
