技術說明

本發明係關於一種載子傳輸材料，其係為由至少一芳烴化合物與至少一多環性芳烴化合物經反應所製得之一分子化合物，且該分子化合物具有至少一可交聯官能基，使得該分子化合物可經由加熱或者照射紫外光的方式產生交聯反應。因此，當此材料被應用於有機發光二極體之內時，經交聯反應而硬化之該載子傳輸材料係不會受到次一層塗佈材料內溶劑的影響而發生部分溶解的現象。並且，經由實驗證明，以此載子傳輸材料作為有機發光二極體的電洞傳輸層之時，其會同時發揮電子侷限之功效，是以能夠提升有機發光二極體的元件效率，尤其在高亮度的情況下。 The present invention relates to provides a carrier transport material formed by completing a reaction process of at least one aromatic compound and at least one polycyclic aromatic hydrocarbons (PAHs), wherein a cross linking reaction can be activated in the molecular compound through heating or ultraviolet irradiation because the molecular compound has at least one cross-linkable functional group. Therefore, when the carrier transport material is applied in an OLED, the carrier transport material would not be dissolved by the solvent included in the next coated material because the carrier transport material has been cured after the cross linking reaction is carried out. Moreover, because the carrier transport material would simultaneously perform an electron confining functionality when being used as a hole transport layer, the device efficiency of the OLED having the carrier transport material is obviously enhanced during the high-brightness operation especially.
