技術說明

合成9,10號碳蒽取代之衍生物其具有電子傳輸性質苯並咪唑 (benzimidazole)單邊取代之monoBizAn，另以苯並咪唑進行雙邊取代得DiBizAn，藉由這些設計試著去提高分子的電子移動速率與提高TTA-UC的效率，以利我們的分子應用在螢光發光二極體材料上。另合成PhBorAn , and NpBorAn 應用於有機發光二極體元件。 PVK摻混40 wt% PhBorAn為發光材料並以旋轉塗佈的方式製作有機發光二極體元件雙層元件中，最高亮度為281 cd/m2，最大電流效率為0.39 cd/A。。另在暫態螢光測試裡，monoBizAn比ADN有更好的延遲螢光表現，足以證明其具有更好的TTA-UC應用於螢光發光二極體的潛力。 A family of anthracene substituted derivatives on the C-9 and C-10 positions with electron transport property benzimidazole substituted monoBizAn and disubstituted DiBizAn aresynthesized. That can be facilitated the electron transporting ability of anthracene. Anthracene derivatives can improve the performance in the fluorescent light emitting diode by triplet-triplet annihilation photon upconversion (TTA-UC). PhBorAn, and NpBorAn are synthesized and applied in organic light emitting diode. While PVK blends with 40 wt% PhBorAn as the emitting material, the highest brightness is 281 cd/m2, and the maximum current efficiency is 0.39 cd/A by spin coating. In the Transient electroluminescence results, monoBizAn owns better performance in delay fluorescent than ADN. That proves the excellent potential TTA-UC application in fluorescent OLED as compared to ADN.
