| 摘要: | 在相關文獻報導中，具有1,3,4-噁二唑環衍生物為一良好的電子輸送材料，其衍生物可運用在OLED或PLED的發光層上。 本論文研究第一個目的，乃先合成出一系列1,3,4-噁二唑之2,5對稱型與非對稱型之化合物，共有2,5-雙苯類、2-苯-5-吡碇類、2-苯-5-胺基類……等。其中對稱之2,5-二苯基-1,3,4噁二唑之收率最高達到88﹪，非對稱之2-胺基-5-吡啶基-1,3,4-噁二唑收率最高達到77﹪。 第二個重點是將具有吡啶環或苯環之1,3,4-噁二唑螢光化合物，並將此化合物進行螢光性質(UV,PL)之分析，探討取代基的改變對其螢光性質的影響。 第三個重點，嘗試將具有胺基的1,3,4-噁二唑化合物與對二甲胺基苯甲醛脫水縮合，目的在使化合物波長往長波長方向移動，在研究中可以觀察到，最大可向長波長伸長137nm。 最後，由於1,3,4-噁二唑環衍生物並沒有易溶於水的官能基，如SO3H-、OH-…….等，所以水溶性並不好。在本實驗中藉由與氯化三聚氰的三段縮合，以不同的取代基來取代氯化三聚氰上氯的位置，希望藉此法來達到兩個目的。一、提高雜環化合物的螢光強度。二、提高雜環化合物對水的溶解度。 Among relevant report , 1,3,4- oxadiazole derivatives can be used on luminescence layer of OLED or PLED. First purpose in this thesis, synthesis a series of 1, 3, 4-oxadiazole chemicals. Two types of them is 2,5 symmetrical and asymmetric chemical compounds. All of them,2,5-dibenzeyl-、2-benzeyl- 5-pyridine-2-benzene-5-amine-…etc. The 2,5-dibenzeyl-1,3,4-oxadiazole of symmetrical compounds up to rates of 88 ,asymmetrical 2-amine-5-pyridinyl-1,3,4-oxadiazole the rate up to 77. The second point of studying is pyridine or benzene of 1,3,4-oxadiazole chemical compound , and analyze chemical compounds by UV,PL , probe into the impact on its luminescence of different substituent. Third point , a little of 1, 3, 4-oxadiazole have amine try to condensation with 4-Dimethylaminobenzaldehyde, the purpose is to make the wavelength move to the long wave direction, observe under study the longest can extend 137nm . Finally, 1,3,4-oxadiazole derivatives are not easy to dissolve in water , because they don't have the hydrophile organic functions, such as SO3H-, OH- . By condensation with cyanuric chloride , react with different substituent to replace three chloride on cyanuric chloride , hope to use this way to achieve two purposes . First, improve the luminous intensity of the heterocyclic compounds. Second, improve the solubility of heterocyclic compounds. |
