ABSTRACT:
A fluorine-containing compound is represented by Formula 1 below:wherein R1a, R1b, R2a, and R2bare each independently a hydrogen atom, a substituted or unsubstituted C1-C30 alkyl group, a substituted or unsubstituted C1-C30 alkoxy group, a substituted or unsubstituted C6-C30 aryl group, a substituted or unsubstituted C6-C30 aryloxy group, a substituted or unsubstituted C4-C30 heteroaryl group, a substituted or unsubstituted C6-C30 condensed polycyclic group, a hydroxy group, halogen, a cyano group, or a substituted or unsubstituted amino group, and adjacent groups selected from R1a, R1b, R2a, and R2bmay join together to form a saturated or unsaturated carbon ring; n and m are each independently an integer of 0 to 5; Ar1aand Ar1bare each independently a C6-C30 aryl group which is unsubstituted or substituted by at least one fluorine or a C4-C30 heteroaryl group which is unsubstituted or substituted by at least one fluorine; and Ar2is a substituted or unsubstituted C6-C30 aryl group or a substituted or unsubstituted C2-C30 heteroaryl group. The fluorine-containing compound has good electrical characteristics and charge transport capability, and thus, is useful as a hole injection material, a hole transport material, and/or an emitting material for fluorescent or phosphorescent devices capable of producing light of a full spectrum of colors, including red, green, blue, and white. Thus, the fluorine-containing compound can be used to produce organic light-emitting devices with high efficiency, a low driving voltage, high brightness, and a long lifetime.
