Description

technical field [0001] The invention relates to the field of photoelectric technology, in particular to an organic photoelectric material, a preparation method thereof and an organic electroluminescence device comprising the organic photoelectric material. Background technique [0002] The origin of organic light emitting diode (OLED) can be traced back to the 1960s. Pope et al. used anthracene single crystal to apply DC voltage to make it emit light, but due to high driving voltage (100V) and luminous brightness And the efficiency is relatively low, and it has not attracted much attention. With the continuous improvement of technology. In 1987, C.W.Tang et al. of Kodak Company used 8-hydroxyquinoline aluminum (AIq3) as the light-emitting material, and made OLED with double-layer sandwich structure by vacuum evaporation method. The voltage is only a few volts, and the brightness can reach up to 1000cd / m 2 , thus marking an important step toward practical use of OLEDs, thus...
