A Class of Asymmetric Donor-Acceptor Type Organic Red Fluorescent Small Molecule Materials and Its Application in Organic Electroluminescent Devices |
| abstract |
An asymmetric donor-acceptor type organic red fluorescent small molecule material and its application in the preparation of organic electroluminescent devices belong to the technical field of organic electroluminescent materials. The present invention utilizes the Suzuki coupling reaction to connect the donor acceptor through linear conjugation, which can realize high-efficiency red light emission. When preparing red light doped devices, by using different matrixes and optimizing the doping concentration, a better In addition, the molecular structure that tends to be planar can use triplet excitons to emit light through triplet-triplet annihilation. The compound obtained in the present invention has a very high fluorescence quantum yield, and the maximum external quantum efficiency of its non-doped red light device is 6.66%, and the external quantum efficiency is 6.51% and 5.11% respectively when the brightness is 100 and 1000cd m -2 , and the efficiency The roll-off is small. The turn-on voltage is low at 2.6V, and the comprehensive performance of the device is at the leading level among organic red fluorescent materials, and it is expected to realize commercial application. |
