摘要: 本研究將含硼咔唑衍生物和茀以Suzuki coupling反應聚合而製備出主鏈含不同carbazole/fluorene比例之共軛高分子,依側鏈共軛長度之不同又可分成polyfluorene-co-9-(4-(dimesitylboryl)phenyl)-9H- carbazole (PFCzPhB) 和polyfluorene-co-9-(4-(5-(dimesitylboryl) thiophen-2-yl)phenyl)-9H-carbazole (PFCzPhThB) 二系列藍光共軛高分子。在高分子主鏈中導入fluorene可以有效提升共軛長度,而3,6-carbazole衍生物可以有效抑制PF所產生之鏈聚集放光,且擁有較高的HOMO能階,在高分子中導入不同程度之咔唑含量可以調控高分子之HOMO能階。所合成之共軛高分子擁有良好的溶解度,在室溫下可溶於大部分溶劑當中,並且擁有很高的熱穩定性。所合成之共軛高分子在薄膜態和甲苯溶液下螢光光譜放射波長皆在藍光範圍內,在甲苯溶液所量測之量子效率範圍在0.47~0.6。 元件製備是以PEDOT : PSS為電洞傳遞層,TPBI 為電子傳遞層,LiF為電子注入層,將共軛高分子當作發光層,使電子/電洞在發光層中再結合而產生光,並加以探討元件在光色和亮度上之表現,元件結構為ITO/PEDOT:PSS/Poylmer/TPBI/LiF/Al,結果顯示PFCzPhThB系列之共軛高分子發光亮度最高,所量測之最大亮度可達445 cd/m2、最大發光效率為0.51 cd/A、CIE值為 (0.16, 0.11)、電激發光波長為442 nm,此元件經電激發光後,光色最接近正藍光,且擁有良好的發光效率。
Carbazole/fluorene-based copolymers with dimestylboron pendants were synthesized by Suzuki polymerization for blue light-emitting diodes. Their compositions and physical properties were determined by gel permeation chromatography, NMR, UV absorption, elemental analysis, thermogravimetry, photoluminescence, and quantum yield measurements. The copolymers exhibited good thermal stability and blue emission in both solution and solid state. Cyclic voltammetry showed that the incorporation of dimesitylboranes-containing carbazole units (CzPhB, CzPhThB) into the polyfluorene (PF) backbone raised HOMO energy levels, and thus facilitated hole injection into the copolymers from the indium tin oxide (ITO) anode. Turn-on voltages of 4.5-8.5 V, maximum brightness of 436 cd/m2 and luminescence efficiency of 0.51 cd/A were obtained for the copolymer devices.
