| titleOfInvention | Blue thermally active delayed fluorescent materials based on trifluoromethylpyridine derivative acceptors and their applications |
| abstract | The invention belongs to the technical field of organic electroluminescent materials, and in particular relates to a class of blue thermally active delayed fluorescence (TADF) materials based on trifluoromethylpyridine derivative acceptors and a preparation method and application thereof. Trifluoromethylpyridine has the advantages of moderate electron withdrawing properties and easy chemical modification, and is a good semiconductor electron acceptor unit. The invention provides a new type of electron acceptor structure trifluoromethyl pyridine unit, constructs D-π-A type blue light TADF material, the intramolecular donor and the acceptor unit are connected by a phenyl π bridge, which can effectively reduce the number of donors. The spatial overlap between the bulk unit HOMO and the acceptor unit LUMO results in a smaller ΔE ST , which promotes reverse intersystem jumping performance, enables fast transitions from T1 to S1 states, and reduces nonradiative transitions of molecules, Improve the luminous efficiency of the material. |
