Abstract

A condensed cyclic compound and an organic light-emitting device including the same.

First claim

What is claimed is:

1. An organic light-emitting device comprising:
a first electrode;
a second electrode; and
an organic layer disposed between the first electrode and the second electrode and comprising an emission layer,
wherein the emission layer comprises a condensed cyclic compound represented by Formula 1 and FIr6, wherein the emission layer emits blue light:
A 11 -L 11 -L 12 -A 12 ,  Formula 1

wherein, in Formula 1,
i) A 11 is a group represented by Formula 4-3, and A 12 is a group represented by one of Formulae 5-3, 5-6, 5-10, 5-17, 5-21, 5-25, 5-32, 5-36, 5-40, 5-43, or 5-101 to 5-104; or
ii) A 11 is a group represented by Formula 4-101, and A 12 is a group represented by one of Formulae 5-3, 5-6, 5-10, 5-17, 5-21, 5-25, 5-32, 5-36, 5-40, or 5-43,
L 11 is a group represented by one of Formulae 2-15, 2-22, 2-23, or 2-102, and L 12 is a group represented by one of Formulae 3-15, 3-22, or 3-23, or
L 11 is a group represented by one of Formulae 2-15, 2-22, or 2-23, and L 12 is a group represented by one of Formulae 3-15, 3-22, 3-23, or 3-102, and
wherein the condensed cyclic compound comprises two or three cyano groups:

wherein:
R 11a to R 11d and R 12a to R 12d , R 13a to R 13d , R 14a to R 14d , R 15a to R 15d , and R 16a to R 16d , R 21a to R 21d , R 31a to R 31d are each independently hydrogen or deuterium, and
* and *′ each indicate a binding site to a neighboring atom.

2. The organic light-emitting device of claim 1 , wherein in the condensed cyclic compound,
i) A 11 is a group represented by Formulae 4-3 or 4-101, and A 12 is a group represented by Formulae 5-3, 5-6, 5-10, 5-17, 5-21, 5-25, 5-32, 5-36, 5-40, or 5-43; or
ii) A 11 is a group represented by Formula 4-3, and A 12 is a group represented by Formulae 5-3, 5-6, 5-10, 5-17, 5-21, 5-25, 5-32, 5-36, 5-40, 5-43, or 5-101 to 5-104.

3. The organic light-emitting device of claim 1 , wherein in the condensed cyclic compound,
i) A 11 is a group represented by Formula 4-3, and A 12 is a group represented by Formulae 5-3, 5-6, 5-10, 5-14, 5-17, 5-21, 5-25, 5-32, 5-36, 5-40, 5-43, or 5-101 to 5-104; or
ii) A 11 is a group represented by Formula 4-101, and A 12 is a group represented by Formulae 5-3, 5-6, 5-10, 5-17, 5-21, 5-25, 5-32, 5-36, 5-40, or 5-43.

4. The organic light-emitting device of claim 1 , wherein in the condensed cyclic compound,
i) L 11 is a group represented by Formula 2-15, and L 12 is a group represented by Formula 3-102;
ii) L 11 is a group represented by Formula 2-102, and L 12 is represented by Formula 3-15;
iii) L 11 is a group represented by Formula 2-15, and L 12 is a group represented by Formula 3-15;
iv) L 11 is a group represented by Formulae 2-22 to 2-23, and L 12 is a group represented by Formula 3-102; or
v) L 11 is a group represented by Formula 2-102, and L 12 is a group represented by Formulae 3-22 to 2-23.
