- Indenoanthracene derivative compound and application thereof
-
The invention discloses an indenoanthracene derivative compound and application thereof and belongs to the technical field of organic electroluminescent materials. A general molecular formula of the compound is shown as a formula (I), wherein L1, L2 and L3 are phenylene or substituted phenylene, n is any integer in a range of 0 to 3, Ar1 and Ar2 are the same or different and each of the Ar1 and the Ar2 independently represents an electron donor group; X can be a C atom, an O atom, an S atom, an N atom and a Si atom; A represents a diphenylphosphine oxide molecule or dibenzyl boron molecule derivative. The compound provided by the invention is used as a doping material and/or a main material of an OLED (Organic Light Emitting Diode), and high brightness, low voltage, high efficiency and long service life of organic electroluminescence devices can be realized; a material prepared from the compounds has relatively high thermal stability, can be used for remarkably improving the luminescent stability of luminescent devices and is widely applied to OLED luminescent devices and display devices.
