热激活延迟荧光（TADF）π共轭聚合物被开发用于溶液加工的TADF-OLED。基于二苯甲酮的交替供体-受体结构有助于小的Δ E-ST，使得能够通过TADF有效地收集激子。使用TADF聚合物作为发射体的溶液处理的OLED可以实现高达9.3%的高最大外部电致发光效率。
Thermally activated delayed fluorescence (TADF) pi-conjugated polymers are developed for solution-processed TADF-OLEDs. Benzophenone-based alternating donor-acceptor structures contribute to the small Delta E-ST, enabling efficient exciton-harvesting through TADF. Solution-processed OLEDs using the TADF polymers as emitters can achieve high maximum external electroluminescence efficiencies of up to 9.3%.
