Abstract
Official abstract text for this publication.
An organic compound is described. An organic electroluminescence device comprises the organic compound, as a host of an emissive layer, as a dopant of an emissive layer, or as an electron transporting layer. The organic compound of the following formula may lower a driving voltage or increase a current efficiency or a half-life of the organic electroluminescence device.The same definition as described in the present invention.
First claim
Opening claim text (preview).
What is claimed is: 1. An organic compound selected from the group consisting of: wherein X represents a divalent bridge selected from the group consisting of O, S, Se, NR 3 and SiR 4 R 5 ; wherein R 6 represents no substitution, mono substitution or di substitutions, and each of the substitutions is selected from the group consisting of halogen, trifluoromethyl, cyano, nitro, silyl, and combinations thereof; wherein R 2 represents mono to the maximum allowable substitution, or no substitution; wherein ring A represents a monocyclic aromatic hydrocarbyl or a polycyclic aromatic hydrocarbyl having 2, 3 or 4 fused rings; wherein ring B is one of the following: and wherein each of R 1 to R 5 is hydrogen or a substituent selected from the group consisting of alkyl, aryl, aralkyl, heteroaryl, and combinations thereof. 2. An organic compound selected from the group consisting of:
