Materials for light emitting devices consisting of novel compounds and light emitting devices using the same

摘要

Disclosed are a compound represented by general formula (IA) or (IB), a material for a light emitting device consisting of the compound, and the light emitting device comprising the material. wherein R11, R12 and R13 each represents a hydrogen atom, an aliphatic hydrocarbon group, an aryl group or a heterocyclic group; L1 represents a connecting group; R11 and R12, R11 and L1, and R12 and L1 may each combine with each other to form a ring when possible; R14, R15, R16 and R17 each represents a hydrogen atom or a substituent; and R13 to R17 may each combine with each of R11 to R17 or L1 to form a ring when possible. wherein R1 and R2 each represents a hydrogen atom, an aliphatic hydrocarbon group, an aryl group or a heterocyclic group; Z1 represents an atomic group necessary to form a heterocycle; L represents a connecting group; and X represents O, S, Se, Te or N-R, wherein R represents a hydrogen atom, an aliphatic hydrocarbon group, an aryl group or a heterocyclic group.
