Abstract

The invention provides a composition comprising at least one dopant, and a polymer containing at least one unit selected from the structure I shown in the specification, wherein M is selected from Fe, Co, or Ni; R1, R2, R3 , R4 and R5 are independently selected from hydrogen, deuterium, halogen, substituted or unsubstituted (C1-C16) alkyl, substituted or unsubstituted (C6-C16) aryl, substituted or unsubstituted (C3-C16) cycloalkyl, substituted or unsubstituted 5- to 7-membered heterocycloalkyl group, substituted or unsubstituted (C6-C16) aryl condensed with one or more cycloalkyls; 5- to 7- membered heterocycloalkyl group condensed with one or more substituted or unsubstituted aromatic rings or (C3-C16) cycloalkyl condensed with one or more substituted or unsubstituted aromatic rings, substituted or unsubstituted (C1-C16) silyl, cyano, nitro or hydroxyl; n is greater than or equal to 1; x is 0-4; y is 0-5; the dopant is a P-type dopant. The polymers containing and free of dopants can be used to prepare films and electronic devices, such as an organic light emitting diode (OLED).

Description

technical field [0001] The present invention relates to an organometallic polymer composition, a preparation method thereof, and an organic light-emitting diode manufactured from the organometallic polymer. Background technique [0002] An OLED (Organic Light Emitting Diode) is a light emitting diode (LED) in which the emissive electroluminescent layer is a film of an organic compound that emits light in response to an electric current. A typical OLED has a multi-layer structure, and usually includes an indium tin oxide (ITO) anode, and a metal cathode. Several organic layers are sandwiched between the ITO anode and metal cathode, such as hole injection layer (HIL), hole transport layer (HTL), light emitting material layer (EML), electron transport layer (ETL), and electron injection layer (EIL). To facilitate hole injection, and to obtain a smooth surface, a hole injection layer (HIL) between the ITO anode and the hole transport layer is often desirable. The most commonl...
