臺灣博碩士論文加值系統

本論文分為二部份，是針對高熱穩定性的有機電激發光二極體之藍光發光材料之合成與性質及元件做討論。
在A部份中，為了減少9,10-diphenylanthracene (DPA)因良好的共平面特性，導致蒸鍍成固態薄膜時其分子間堆疊情況嚴重，我們選擇於9,10-diphenylanthracene兩端的diphenyl之4或4’位置上導入一個較大且剛硬的取代基，合成出二個新的OLED藍光材料(PTPBPA、BTPBPA)，結果顯示這些化合物也展現了較高的熱穩定性及玻璃轉移溫度，也具有相對較高的量子效率，所發出藍色光色也較純。
在B部份中，為了改善DPVBi低玻璃轉移溫度的缺點，我們導入fluorene的結構來取代DPVBi中的biphenyl，並在fluorene碳-9的位置上導入不同之取代基，合成三個新的藍光材料；結果顯示此三個化合物已明顯提升了玻璃轉移溫度，且熱穩定性及量子效率也相對的提升，而於元件製作及表現上，結果也顯示這系列的化合物在元件的製程中亦是良好的藍光emitter及host材料。

This thesis is divided into two parts about the synthesis and characterization of blue-emitting materials, which exhibit pronounced thermal stabilities. We also report the fabrication and performances of OLEDs based on these materials.
In part A, we introduce bulky and rigid groups each on the place, 4 or 4’ of both side of diphenyl in 9,10-diphenylanthracene to reduce the good co-planar properties which may cause the serious aggregation between molecules when vaporized. We synthesize two new blue light-emitting materials which are PTPBPA and BTPBPA. All of them exhibit good thermal stabilities, high glass transition temperatures and higher quantum efficiency.
In part B, we introduce the fluorene structure to replace the biphenyl of DPVBi in order to improve the low Tg of DPVBi. And we introduce different group on the 9,9 of fluorene to synthesis three new blue light-emitting materials. All of them exhibit better thermal stability, higher glass transition temperature, and higher quantum efficiency to DPVBi. The devices include these new blue-emitting materials show good performance.
