A fluorine-containing compound is represented by Formula 1 below:
wherein R
1a
, R
1b
, R
2a
, and R
2b
are 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 R
1a
, R
1b
, R
2a
, and R
2b
may join together to form a saturated or unsaturated carbon ring; n and m are each independently an integer of 0 to 5; Ar
1a
and Ar
1b
are 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 Ar
2
is 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.
一种含氟化合物由下面的化学式1表示:其中R1a、R1b、R2a和R2b分别是氢原子、取代或未取代的C1-C30烷基、取代或未取代的C1-C30烷氧基、取代或未取代的C6-C30芳基、取代或未取代的C6-C30芳氧基、取代或未取代的C4-C30杂芳基、取代或未取代的C6-C30紧凑多环基团、羟基、卤素、氰基或取代或未取代的氨基,且从R1a、R1b、R2a和R2b中选择的相邻基团可以结合在一起形成饱和或不饱和碳环;n和m分别是0到5之间的整数;Ar1a和Ar1b分别是未取代或至少一个氟取代的C6-C30芳基或未取代或至少一个氟取代的C4-C30杂芳基;Ar2是取代或未取代的C6-C30芳基或取代或未取代的C2-C30杂芳基。该含氟化合物具有良好的电特性和电荷传输能力,因此,可用作发光或磷光器件的孔注入材料、孔传输材料和/或发射材料,能够产生全光谱颜色的光,包括红色、绿色、蓝色和白色。因此,该含氟化合物可用于制备具有高效率、低驱动电压、高亮度和长寿命的有机发光器件。
