技術說明

選擇以N-phenylcarbazole(NPC)和1,3-Bis(N-carbazolyl)benzene(mCP)結構為核心，於鄰位分別接上數目不同之具有傳電子特性的苯並咪唑(benzimidazole)，形成三支雙偶極主題材料 o-CbzBz, o-CbzDiBz和o-DiCbzBz。利用benzimidazole做為傳電子基團搭配常見之傳電洞基團Carbazole進行單一苯環鄰位修飾的方法，達成高效率磷光有機發光二極體(OLED)之雙偶極主發光體。 Using N-phenylcarbazole (NPC) and 1,3-Bis (N-carbazolyl) benzene (mCP) as the core structure, were connected in the ortho position with a different number of electron transfer properties benzimidazole (benzimidazole), forming a three-supporting dual dipole thematic material o-CbzBz, o-CbzDiBz and o-DiCbzBz. As the use of benzimidazole group with a common transmission electron Chuan hole group Carbazole be a single benzene ring ortho modification methods, to achieve high efficiency phosphorescent OLED (OLED) of the dual dipole main emitters.
