COMPOUND FOR ORGANIC LIGHT-EMITTING DEVICE HAVING DOUBLE CORE STRUCTURE AND ORGANIC LIGHT-EMITTING DEVICE USING SAME

摘要

The present invention relates to a compound for an organic light-emitting device having a double core structure in molecules thereof, and to a light-emitting device using the compound. The present invention provides a compound for an organic light-emitting device having a double core (A-B) structure in molecules thereof expressed by the following chemical formula 1. The double core structure is configured in that light-emitting materials having superior light-emitting efficiency are combined to form a double core, and has structural characteristics in that two cores (A-B) of an aromatic ring having a planar structure are combined at a twisted angle, and thus may exhibit high stability in a solution process and a long service life of the device due to high light-emitting efficiency and improved solubility. Further, a device using, as a light-emitting layer, the compound for an organic light-emitting device according to the present invention may exhibit high light-emitting efficiency and long service life as compared with cases using conventional compounds having a single core. Chemical formula 1 : Ar1-(A-B)-Ar2 (where A, B, Ar1 or Ar2 is as defined in the specification).
