-
Paragraph 0052; 0054-0057, (2019/10/15)
The invention relates to an organic compound; the organic compound is as shown in a formula (1), and the formula (1) is described in the description, wherein the dotted circle represents a benzene ring structure, and indole derivative groups positioned at the two sides of the benzene ring structure are fused into indolocarbazole derivatives by means of the benzene ring structure; X1-X8 is CR or N;one of Ar1 and Ar2 is selected from pi-absence electron-type aromatic groups of C3-C30; R is selected from hydrogen, aliphatic hydrocarbon groups of C1-C4, aryl groups of C6-C30 and heteroaryl groupsof C3-C30; when multiple Rs exist, all the Rs can be the same or different; m and n are respectively integers within a range of 1-4; p is 1 or 2; L1 and L2 are respectively and independently selectedfrom a single bond, arylene groups of C6-C12 or hetero-arylene groups of C3-C12; when substituents exist in the groups, the substituents are respectively and independently selected from halogen, alkyl or cycloalkyl groups of C1-C10, alkenyl or cycloalkenyl groups of C2-C6, alkoxy or thioalkoxy groups of C1-C6, monocyclic aryl or fused ring aryl groups of C6-C30, monocyclic heteroaryl or fused ring heteroaryl groups of C3-C30, or a combined structure of the groups.
Naphtho-fluorene carbazole compound and application thereof
-
Paragraph 0086; 0089-0091, (2018/03/26)
The invention belongs to the field of organic electroluminescence, and in particular relates to a naphtho-fluorene carbazole compound and application thereof. An OLED device manufactured by taking thesynthesized organic compound as a main body light-emitting material can be applied in the fields of AM drive OLED display, PM drive OLED display or OLED illumination. The external quantum efficiency,the power efficiency and the current efficiency of the device are greatly improved, and the service life of the device is obviously prolonged, so that the naphtho-fluorene carbazole compound has thegood market prospect.
