A kind of bitridentate iridium complex modified by pterene, preparation method and organic electroluminescence device |
| abstract |
The invention discloses a bitridentate iridium complex modified by pterylene, a preparation method and an organic electroluminescence device, and belongs to the field of organic optoelectronic materials. Wherein, the bitridentate iridium complex organic electrophosphorescent material modified by pterene of the present invention solves the problem that the existing bitridentate iridium complex is particularly sensitive to doping concentration and is particularly prone to concentration quenching; the preparation steps are as follows: : add 2-acetyl-6-bromopyridine derivative in triptycene 2 boronic acid derivatives, simultaneously in the presence of alkali, catalyst and solvent, react for a period of time to obtain intermediate; this intermediate is then coupled, cyclized The reaction obtains a ligand; the ligand is reacted with iridium trichloride, and then alkylated and ion exchanged to obtain a bitridentate iridium complex modified by pterene; and the bitridentate iridium complex of the present invention is used in an organic electroluminescent device. It has application potential in the light-emitting layer. |
