dc.description.abstract | 聚集誘導放光現象 (Aggregation-induced emission, AIE) 從2001年被提出以後,各種相關的研究相繼展開,具有該現象的分子用途甚廣。在本研究中以具有聚集誘導放光現象的四苯基乙烯 (Tetraphenylethylene, TPE) 為主體,並引入三咔唑基團 (Tricarbazole, tcbz) 在間位及對位進行取代,以提高分子熱穩定性,並調整其電洞傳輸能力,以便應用於藍光螢光非混摻有機發光二極體元件製作;另外由於三咔唑基團有電聚合特性,我們也以電聚合方式製作電致變色薄膜並觀察到顏色變化。
在元件表現部分,我們以 tcbz3B 作為發光層材料,製作螢光非混摻有機發光二極體元件,測試結果最大亮度可達 2046 cd/m2,最大電流效率為 4.7 cd/A,最大發光功率為 4.7 lm/w,最大外部量子效率為 2.6%,在螢光發光材料中有不錯的表現。 同時,我們也把 4tcbzTPE、3tcbzTPE 電聚合於ITO基板上,應用於電致變色元件的製作,元件可由幾近透明,隨電流調整而變為淺綠色進而深綠色,變色過程可以反覆操作。另於電聚合的過程中成功以 4tcbzTPE、tcbz3B 製作出具有螢光特性的電聚合薄膜。 而在研究過程中也發現 4tcbzTPE 具有摩擦變色的現象,經摩擦後4tcbzTPE 的螢光峰值會由444 nm紅移至483 nm,經溶劑浸泡後可逆;而4tcbz3B 具有熱致變色現象,加熱 300℃,肉眼可見tcbz3B 粉末由白色變黃色,且螢光性質消失。 | zh_TW |
dc.description.abstract | The phenomenon of aggregation induced emission (AIE) has been mentioned by Tang’s group since 2001. After that, lots of researches about AIE have been published. The molecule with AIE behavior can be used in many different fields. In our research, tetraphenylethylene is introduced as main unit, which is a kind of AIE gens and then tricarbazole functional group is introduced at mata and para position of tetraphenylethylene to improve thermal stability and adjust hole transporting ability for applications of blue Non-doped Organic Light Emitting Diodes (OLED) . The molecule synthesized containing tricarbazole functional group results in electropolymerizaton and to make electrochromic film.
Before optimising, the device with tcbz3B as emitting layer exhibits maximum luminance of 2064 cd/m2, the maximum current efficiency (CE) of 4.7 cd/A, the maximum power efficiency (PE) of 4.7 lm/w, and the maximum external quantum efficiency (EQE) of 2.6%. 4tcbzTPE and 3tcbzTPE are used to make electrochromic devices and the color of the device changing from transparent to dark yellow and finally become olive is noted during oxidation procedures. The color changing of the electrochromic devices is reversible. In addition, 4tcbzTPE and tcbz3B are used to make electropolymer thin film with light emitting effect. During the research, we also found that 4tcbzTPE has Mechanochromic effect. The fluorescence of 4tcbzTPE will change from 444 nm to 483 nm after grinding. The tcbz3B has Thermochromic effect, we can notice the color of powder changing from white to yellow, and the fluorescence weakening as the temperature increasing. | en |
