Abstract
Provided are a condensed cyclic compound and an organic light-emitting device including the same. The material is represented by the formula A2-(A1)n1, wherein A2 may be selected from groups represented by Formula 2, A1 may be selected from groups represented by Formulae 2-1 to 2-4, and n1 may be an integer selected from 1 to 5:Organic light-emitting devices manufactured using this material were found to have lower driving voltages, higher brightness values, higher efficiencies, and longer half-lifespans.
