OLED에서 인광재료는 형광재료보다 효율이 높아 현재료는 우수한 소재로 인정되고 있지만 유기금속화함물에 기반된 고가의 재료이므로 이에 대한 저가 유기 화합물로의 대체 노력이 많다. 열적지연 형광체가 가장 유망한 개념의 물질인데, 이에 대해 잘 정리된 분석자료로서 제시한다.
The design of thermally activated delayed fluorescence (TADF) materials both as emitters and as hosts is an exploding area of research. The replacement of phosphorescent metal complexes with inexpensive organic compounds in electroluminescent (EL) devices that demonstrate comparable performance metrics is paradigm shifting, as these new materials offer the possibility of developing low-cost lighting and displays. Here, a comprehensive review of TADF materials is presented, with a focus on linking their optoelectronic behavior with the performance of the organic light-emitting diode (OLED) and related EL devices. TADF emitters are cross-compared within specific color ranges, with a focus on blue, green？yellow, orange？red, and white OLEDs. Organic small-molecule, dendrimer, polymer, and exciplex emitters are all discussed within this review, as is their use as host materials. Correlations are provided between the structure of the TADF materials and their optoelectronic properties. The success of TADF materials has ushered in the next generation of OLEDs.
