Abstract
The OLED in the present invention comprises an anode, a cathode, and one or multiple organic layers, and the organic layer at least contains one kind of material with the following chemical formula I. The OLEDs made by this organic light emitting material have advantages such as good light emitting efficiency, excellent color purity and long lifetime.
Claims13
An OLED comprises an anode, a cathode, and one or more organic layers. At least one layer in the organic layers includes a kind of material with the following chemical structural formula I:
- Wherein, R1-R3 independently represent hydrogen, deuterium, halogen, cyano, nitro, C1-C8 alkyl, C1-C8 alkoxy, C6-C30 aryl unsubstituted or substituted by one or more substituent group R, C3-C30 heteroaryl containing one or more heteroatoms unsubstituted or substituted by one or more substituent group R, C2-C8 alkenyl unsubstituted or substituted by one or more substituent group R, C2-C8 alkynyl unsubstituted or substituted by one or more substituent group R, C8-C30 diaryl vinyl unsubstituted or substituted by one or more substituent group R, C8-C30 diaryl ethynyl, trialkyl silicon unsubstituted or substituted by one or more substituent group R, C6-C30 triaryl silicon unsubstituted or substituted by one or more substituent group R, C6-C30 diaryl phosphonoso unsubstituted or substituted by one or more substituent group R, C6-C30 aryl carbonyl unsubstituted or substituted by one or more substituent group R, C6-C30 aryl sulfenyl unsubstituted or substituted by one or more substituent group R, C6-C30 aryl fused ring unsubstituted or substituted by one or more substituent group R, C6-C30 substituted or unsubstituted heteroatom-containing aryl fused ring, C6-C30 carbazolyl unsubstituted or substituted by one or more substituent group R, C6-C30 diaryl amine unsubstituted or substituted by one or more substituent group R, or a spiral structure formed between two R2 groups, and the said heteroatoms are B, O, S, N, Se;
- Ar1-Ar2 represent independently C6-C30 aryl containing one or more substituent group R, aryl fused ring unsubstituted or substituted by one or more substituent group R, C6-C30 carbazolyl unsubstituted or substituted by one or more substituent group R, C6-C30 tri-aromatic amine unsubstituted or substituted by one or more substituent group R.
- Where, R represent independently alkyl, five-or six-membered ring aryl, alkoxy, deuterium, halogen, cyano, nitro, amino.
