臺灣博碩士論文加值系統

本論文係利用�w�t(carbazole)為原料，以KMnO4當環化試劑製備發光小分子材料，並經由NMR、EA、IR、DSC、TGA、UV-VIS、CV、PL光譜數據及EL測試，以探討含�w�t系列以及�w�t含�G�H化合物之結構、物性及光電性質影響。
在熱穩定性質方面，所合成化合物均具有良好的的熱裂解溫度(Td＞306℃)。在玻璃轉化溫度(glass transition temperature，Tg)方面，化合物有Tg點，而且Tg點低，屬於不理想的。
由PL結果中，發現取代基的改變，歸納�'�t化合物氮上取代基為長碳鏈有影響，而氮上取代基為�'基沒有影響放光的波長。
元件製作方面，以真空蒸鍍的方式成膜而製成元件。測試時，由於發光時間過短，無法得到EL圖譜為本論文之遺憾。歸納原因，由於電洞傳輸速度比電子傳輸速度快太多。因此加入一材質使電洞傳輸速度降低，或著改變元件設計。

In this thesis the luminescent organic material was synthesized using carbazole as a starting material and KMnO4 as a cyclization reagent. The structure, physical and electroluminiecent properties for the obtained products including carbazole series and their indole derivatives were studied by the analysis of NMR elemental analysis IR, DSC,TGA,UV-VIS,CV,PL spectrum and EL test.
For the thermal stability , all synthesized compounds had good thermal decomposition temperatures ,but low glass transition temperatures.
The result for PL spectrum analysis indicated that substituted groups for the compounds with a long chain on N position effect the PL spectrum but with benzyl group on N position not.
The EL device was fabricated by depositing as a film in vacumn and tested to emit too instantly to gain the EL spectrum . This was attributed to the larger velocity for hole-transport than electron-transport.
This can be modified by adding the material which can lower the velocity of hole-transport or enhancing the thickness of the deposited film for emitting layer.
