Abstract
The present disclosure describes an electroluminescent material which is formed of a compound having a structure of Formula (I), an OLED display panel utilizing the compound and an electronic device having the OLED display panel. The OLED display panel includes a first electrode, a second electrode, and an organic thin film layer disposed between the first electrode and the second electrode. The organic thin film layer comprises an electron transport layer which comprises any one or a combination of at least two of the compounds. The electroluminescent material has a triplet energy level Eof ≥2.7 eV, a HOMO energy level of ≤−5.85 eV, and a glass transition temperature of >120° C. This compound improves luminous efficiency in the OLED display panel and the electronic device.
