Abstract: The present disclosure relates to an organic photoelectric functional material, a method for the same, usage of the same, and a light-emitting device. The organic photoelectric functional material has electroluminescence and electron transportation properties. The organic photoelectric functional material is selected from a group consisting of compounds represented by formula I and formula II, and combinations thereof. If the organic photoelectric functional material is used as an electroluminescence material, light emission thereof can be adjusted by modifying a quinoline moiety thereof with a substituent, and a luminous range thereof is about 345 nm to about 700 nm.

Abstract: The present invention belongs to the field of organic light emitting materials and discloses an organic metal complex, its preparation method and an application thereof. The metal complex provided by the present invention has a general formula structure as shown in a formula (I). In the present invention, a ligand containing a pyridine unit is introduced into the cyclometalated iridium (trivalent) of the organic metal complex. The obtained hetero complex of the iridium (trivalent) has a light emitting interval ranging from a near infrared region to a blue light region, and has the advantages of wide spectrum application range and low volume production cost, so as to obtain a stable and high-efficient phosphorescent material.

Abstract: Provided are an organic metal complex, its preparation method and light-emitting element containing the complex. The organic metal complex is selected from compounds shown as general formula I and combinations thereof. The ligand containing pyridine unit is introduced into the cyclometalated iridium(III) organic metal complex, and the obtained iridium(III) heterocomplex has a luminous range from near-infrared light to blue light, so that the ppz-Ir structure, which is originally non-luminous, can emit light at room temperature with advantages of wide application scope of spectrum and low cost of massive production.

Abstract: The present disclosure provides a blue luminescent material, and the blue luminescent material is a tertradentate platinum complex having a chemical structure of Formula I comprising a pyridoimidazole carbene platinum structure. The blue luminescent material of the present disclosure may be used in OLED devices and apparatus as a dopant material and emits blue light having a wavelength of 450-490 nm. The present disclosure provides a design route for a material by introducing a pyridoimidazole-type carbene into the ligand of a platinum complex. Since the carbene structure has suitable triplet energy and its carbon-platinum bond is more stable than the nitrogen-platinum bond, the entire spectrum can become narrower, which will promote development of blue luminescent material and improve performances of the devices.
