dc.description.abstract | 熱啟動延遲螢光(TADF)是一種使三重態激子轉化為單重態激子的過程,從而釋放延遲螢光並提高有機發光二極體(OLED)的外量子效率(EQE)的理論上限。此外,大多數激發複合物的最低激發單重態(S1)和三重態(T1)之間的能隙(ΔEST)趨近於零。這意味著它們可以有效地提高反系間穿越(kRISC)的速率,因此非常適合在OLED中使用。值得注意的是,OLED中的電子轉移效率高度依賴於供體分子和受體分子之間的距離,一般來說距離越短,效率越高。在這裡,使用了TrMe@Trz-cage的包合物作為發光材料,並成功通過溶液法製備了一種綠光OLED,實現了達到15.18 %的EQE。這是首次將包合物應用於OLED中,並且具有良好的性能。 | zh_TW |
dc.description.abstract | Thermally Activated Delayed Fluorescence (TADF) is a process that enables the conversion of triplet excitons to singlet excitons, thereby releasing delayed fluorescence and increasing the theoretical upper limit of external quantum efficiency (EQE) in organic light-emitting diodes (OLEDs). Additionally, the energy gap between the lowest excited singlet (S1) and triplet (T1) states (ΔEST) of most exciplexes tends towards zero. This means that they can efficiently increase the rate of reverse intersystem crossing (kRISC), making them well-suited for use in OLEDs. Notably, the electron transfer efficiency in OLEDs depends highly on the distance between donor and acceptor molecules, with shorter distances resulting in higher efficiency. To address this, an inclusion complex called TrMe@Trz-cage was designed as the emitter and successfully used in the fabrication of a green OLED through a solution process, achieving a high EQE of 15.18 %. This is the first time that an inclusion complex has been used in solution-processed OLEDs with good performance. | en |
