▎ 摘　　要

NOVELTY - Blue-light fluorescent organic light emitting diode with hybrid local area load transfer (HLCT) material containing TTA process as main body comprises a substrate, an anode, a hole injection layer, a hole transport layer, a exciton blocking layer, a light emitting layer, an electron transport layer, an electron injection layer and a cathode, where the light emitting layer is composed of a host material and a fluorescent guest dopant. The host material is 2-(4 - (10 - (3 - (9H-carbazol-9-yl) phenyl) - anthryl-9-yl) phenyl) - l-phenyl- -1H - phenanthrene (9, 10-d) imidazole. The guest dopant is N, N - '(3-methyl phenyl) N, N -' (3 - (9-phenyl-9H - fluorene-9-yl) phenyl) - pyrene -1, 6-diamine. USE - Used as blue-light fluorescent organic light emitting diode with hybrid local area load transfer material containing TTA process as main body. ADVANTAGE - The diode: has high efficiency and excellent stability; realizes the energy transfer between host and guest; and provides a way for the preparation of high-performance blue fluorescent OLEDs. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the blue-light fluorescent organic light emitting diode with hybrid local area load transfer material containing TTA process as main body comprising firstly pretreating a glass substrate with an ITO anode performing the lye ultrasound, deionized water washing, high-pressure nitrogen drying, oven baking and ultraviolet ozone treatment and placing the processed ITO anode glass substrate into the coating machine, using the mechanical pump and molecular pump to coating the film, evacuating the machine to a pressure below 1x 104Pa and a hole injection layer, a hole transport layer, an electron blocking layer, a light-emitting layer, an electron transport layer, an electron injection layer and a cathode are sequentially vapor-deposited on the surface of the ITO anode glass substrate.
