Universal bipolar host material containing pyridine group and its preparation and application in organic light-emitting diodes |
| abstract |
The invention belongs to the technical field of organic optoelectronic materials, and discloses a general bipolar host material containing a pyridine group and its preparation and application in organic light-emitting diodes. The structure of the universal bipolar host material containing a pyridine group is as follows, wherein, n is an integer from 1 to 10, R 1 is a hydrogen atom or an alkyl chain, and Ar is an electron donating group of an aromatic ring derivative. The invention also discloses a preparation method of the host material. The host material of the present invention increases triplet energy and has both excellent electron transport performance and hole transport performance; blue, green and red PHOLEDs with excellent performance such as high efficiency and low efficiency roll-off can be prepared, and the host The material is expected to realize high-performance white-light PHOLEDs with a single host. The host material of the present invention is applied to the field of organic optoelectronic devices. |
