摘要

隨科技普遍化，便攜式發光面板顯示器需求量大為提高，其中有機發光二極體(OLED)因具高品質自發光性質可能成為次世代顯示器主流。小分子發光材料常以真空蒸鍍法建構多彩OLEDs，相較之下，大分子發光材料能以溶液塗佈法建構元件，製程簡單、投資成本相對較低，但各色光大分子材料於逐步建構時普遍存在再溶解問題，難以得到高解析圖案化顯示效果，因此，便發展出改善分子本身結構以達圖案化之目的。本實驗構想將芴發光材料與可交聯環氧丙烷官能基結合，使發光層具備光阻性質，透過光罩曝光與顯影動作，克服再溶解困擾，達到光學圖案化目的，即能逐步累積各色發光層定位於同一基材上。
本研究成功合成出帶有可交聯環氧丙烷官能基的fluorene發光層材料，並以H1-NMR, C13-NMR, ATR-FTIR, Mass等儀器鑑定合成的結果。將3-((6-(7-(6-((3-ethyloxetane-3-yl)methoxy)hexyloxy)-9,9-dioctylfluorene)hexyloxy)methyl)-3-ethyloxetane塗佈於玻璃基材上進行曝光工作，塗層發生硬化反應，進而得交聯薄膜。此外，本研究亦製作簡單型光罩服貼於已塗佈單體的基材上，再進行曝光顯影工作，順利得到圖案化效果。此圖案化高分子成品經UV燈照射，可放射得藍光，成功得光學圖案化之目的。

In this study, we have successfully synthesized fluorene light emitting material containing the oxetane crosslinkable group. Then we characterized the monomer by H1-NMR, C13-NMR, ATR-FTIR, and Mass. The monomer was coated on glass substrate and cured by UV irradiation in the air to get thin transparent film. We found that the film can be crosslinked. Then we investigated the possibility of the photo-patterned film. For this purpose, the film was irradiated through a shadow mask. After curing, the film was developed by immersing it into n-hexane, which re-dissolved the non-irradiated areas of the film. Finally, we got the photo-patterned film. According to the findings, this study provides several suggestions for future studies.
