, (2018/03/09)
The invention discloses a pyrimido-isoindole derivative and an organic light-emitting device with the same. The organic light-emitting device comprises a cathode, an anode and one or a plurality of organic matter layers. The organic matter layers are positioned between the cathode and the anode, and at least one of the organic matter layers comprises the pyrimido-isoindole derivative. The pyrimido-isoindole derivative and the organic light-emitting device have the advantages that the pyrimido-isoindole derivative has large conjugation systems and is high in hole mobility and good in hole transport performance; the pyrimido-isoindole derivative is good in heat stability and solubility and favorable for material film formation; the organic light-emitting device with the pyrimido-isoindole derivative used as the corresponding organic matter layer only requires low driving voltages and is high in light-emitting efficiency and light-emitting brightness and long in service life.
