Electron donor compound and preparation method thereof, light emitting device and display device

The invention relates to an electron donor compound, a light-emitting device, a preparation method of the light-emitting device and a display device. The electron donor compound has the following structural groups: each R1 independently selected from hydrogen, a trimethylsilyl group, a cyclohexyl group, a 3-pentyl group, a 4-(9,9'-spirobifluorene) group, a 2-(9,9'-diphenyl fluorene) group or a tetraphenyl vinyl group, wherein each R1 is not hydrogen at the same time. When the electron donor compound provided by the invention is used as an electron donor material to be applied to an interface heterojunction exciplex system, the original contact point of an electron donor and an electron acceptor is isolated by a non-hydrogen substituent, so that electrons and holes are separated in space, according to the invention, electrons of the electron acceptor layer can be prevented or hindered from easily moving into the electron donor layer, so that the electrification problem of quantum dots is avoided or relieved, and the efficiency and the service life of the light-emitting device are improved.

ORGANIC ELECTROLUMINESCENCE AND ORGANIC ELECTROLUMINESCENCE ELEMENT

This invention provides an organic electroluminescent compound, which is represented by the following chemical formula (I). In the above formula, A and A' are each independently R0 or R1, and R0 is 9,9'-spirobifluorene-2'-yl, R1 may be selected from substituted or unsubstituted aryl, heteroaryl or heterocyclyl; and at least one of A and A' must be R0. The compound of the formula (I) may be an electron transport material and thereby improve the luminous efficiency and thermal stability of a light emitting element. This invention further provides an organic electroluminescent element made from the organic electroluminescent compound.
