  • Patent number: 10199583
    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.
