Cyclometalated iridium complex as well as preparation method and application thereof

The invention belongs to the technical field of organic photoelectric materials, and particularly relates to a cyclometalated iridium complex, the structural formula of the cyclometalated iridium complex is shown as a formula I, and n is equal to 2 or 3; wherein R is carbazolyl or diphenylamino group, and L^X is an auxiliary ligand containing N and/or O. The invention also provides a preparation method and application of the iridium complex. Six novel cyclometalated iridium complexes with novel structures are obtained by introducing diphenylamine and carbazole units to a 2phenylbenzothiazole cyclometalated ligand, three light-emitting colors are yellow (TM 1-3, [lambda]Em -560 nm), and three light-emitting colors are red (TM 4-6, lambda Em 618-636 nm); therefore, the emission wavelength of the compound is tuned, and the electroluminescent property of the material is improved by improving the hole transport property of the material.
