An organic light emitting device (OLED) that includes an anode, a cathode, and an organic layer disposed between the anode and the cathode. The organic layer includes a metal compound that comprises a ligand L
A
of Formula I, wherein the dashed lines represent coordination to a metal M.
The metal M is selected from the groups consisting of Os, Ru, Ir, Rh, Pt, Pd, and Cu, and the metal is further coordinated to one or more ligand(s) L
B
, wherein the ligand(s) L
B
can be the same or different if more than one ligand L
B
is present. Optionally one or two of the ligand(s) L
B
can independently link to the ligand L
A
through one of R
1
to R
5
. The invention is also directed to a consumer product that includes an OLED, and the OLED includes an organic layer that includes a metal compound that comprises a ligand L
A
of Formula I.
一种有机发光器件(OLED),包括阳极、阴极和位于阳极和阴极之间的有机层。有机层包括一个包含配体LA的化合物,其中虚线代表与金属M的配位。金属M选自Os、Ru、Ir、Rh、Pt、Pd和Cu组,金属进一步与一个或多个配体LB配位,如果有多个配体LB,则这些配体LB可以相同或不同。可选地,一个或两个配体LB可以独立地通过R1至R5中的一个连接到配体LA。该发明还涉及一种包括OLED的消费产品,该OLED包括一个包含配体LA的化合物的有机层。
