The invention relates to a novel method for modifying the surface of a polysulfone ultrafiltration membrane, used for improving the pollution resistance of a separation membrane. In the invention, by using polysulfone as a surface modification basement membrane, a living radical is generated on the membrane surface with an ultraviolet initiator or a thermal initiator to further graft a hydrophilic monomer on the surface of the membrane, thereby finishing grafting modification to a polysulfone ultrafiltration membrane. The method is convenient to operate, efficiently inhibits generation of polysulfone main chain fracture and also keeps the interception performance of the ultrafiltration membrane. In the prepared ultrafiltration membrane, the hydrophilicity is obviously improved, and the pollution resistance is remarkably enhanced.

The invention discloses an organic electroluminescent device. A light-emitting layer comprises a host material and a guest material. The host material is an exciplex formed by an electron donor material and an electron acceptor material, and the guest material is a thermally activated delayed fluorescent material. The singlet-state energy level of the host material is lower than the singlet-stateenergy level of the guest material. Since the singlet-state energy level of the exciplex as the host material in the light-emitting layer is lower than the singlet-state energy level of the thermallyactivated delayed fluorescent material, the generation of high-energy excitons is prevented, and molecular bond breakage due to high excitation energy is effectively suppressed. The singlet-state energy level of the exciplex is low, which is beneficial to reduce the excitation energy of the excitons in the device, and suppress the triplet state-triplet state annihilation, the triplet state-polaronquenching and the singlet state-triplet annihilation phenomena in the device, thereby reducing the efficiency roll-off of the device and prolonging the service life of the device.
