Abstract
The present specification relates to a hole injection or transfer layer coating composition of an organic light emitting diode comprising an organic metal complex of a transition metal; a fluorine-based polymer comprising sulfonic acid or sulfonate; and an organic solvent, a method for manufacturing an organic light emitting diode and an organic light emitting diode using the same.
Claims20
A hole injection or transfer layer coating composition of an organic light emitting diode, the composition comprising:
- an organic metal complex of a transition metal;
- a polymer comprising a unit of the following Chemical Formula 1;
- and
- an organic solvent:
- in Chemical Formula 1,
- A is at least one selected from an aromatic hydrocarbon ring, a heteroring or a substituted or unsubstituted alkylene group wherein optionally at least one carbon atom of the alkylene group is replaced by O, S, C(═O), S(═O) or S(═O)2;
- X1 is O or S, X2 is CR5R6, O or S, n is an integer of 1 to 10, p is an integer of 1 to 10 and m is an integer of 0 to 10;
- Y is SO3H, SO3Li, SO3Na, SO3K, SO3Rb or SO3Cs;
- and
- R1 to R6 are each independently hydrogen, fluorine, an alkyl group or a fluoroalkyl group, and at least one of R1 and R2 is fluorine.
