Abstract
A condensed polycyclic compound is represented by the following Formula [1]: wherein in Formula [1], R1 to R16 each represent a hydrogen atom, a halogen atom, an alkyl group having 1 to 20 carbon atoms, a substituted amino group, an aryl group that may optionally have a substituent group, or a heterocyclic group that may optionally have a substituent group, provided that at least one of R1, R2, R7 and R8 is an aryl group that may optionally have a substituent group, or a heterocyclic group that may optionally have a substituent group.
Claims6
An organic light emitting device comprising:
- an anode and a cathode;
- and
- a light emitting layer disposed between the anode and the cathode,
- wherein the light emitting layer comprises a host material and a guest material;
- the guest material is a fluorescent material,
- the host material is a condensed polycyclic compound represented by the following Formula [1]:
- wherein in Formula [1],
- R1 to R16 each represent a hydrogen atom, a halogen atom, an alkyl group having 1 to 20 carbon atoms, a substituted amino group, an aryl group that may optionally have a substituent group, or a heterocyclic group that may optionally have a substituent group,
- provided that at least one of R1, R2, R7 and R8 is an aryl group that may optionally have a substituent group, or a heterocyclic group that may optionally have a substituent group.
An organic light emitting device comprising:
- an anode and a cathode;
- and
- a layer comprising an organic compound disposed between the anode and the cathode,
- wherein the layer comprising a hole transporting layer,
- the hole transporting layer comprising a condensed polycyclic compound represented by the following Formula [1]
- wherein in Formula [1],
- R1 to R16 each represent a hydrogen atom, a halogen atom, an alkyl group having 1 to 20 carbon atoms, a substituted amino group, an aryl group that may optionally have a substituent group, or a heterocyclic group that may optionally have a substituent group,
- provided that at least one of R1, R2, R7 and R8 is an aryl group that may optionally have a substituent group, or a heterocyclic group that may optionally have a substituent group.
