Evaporation- and Solution-Process-Feasible Highly Efficient Thianthrene-9,9′,10,10′-Tetraoxide-Based Thermally Activated Delayed Fluorescence Emitters with Reduced Efficiency Roll-Off

A study was conducted to exploit evaporation- and solution-process-feasible thermally Activated Delayed Fluorescence (TADF) materials with reduced efficiency roll-off. Two novel emitters ACRDSO2 and PXZDSO2, containing thianthrene-9,9',10,10'-tetraoxide (TEDSO2), as a brand-new electron-acceptor moiety were designed and synthesized for the investigations. 9,9-Dimethyl-9,10-dihydroacridine (ACR) and phenoxazine (PXZ) with good hole-transporting ability were introduced as the electron-donor units to give a shallow HOMO energy level and thus improved hole injection.

Blue thermal active delayed fluorescence material based on trifluoromethyl pyridine derivative receptor and application thereof

The invention belongs to the technical field of organic electroluminescent materials. The invention particularly relates to a blue thermal active delayed fluorescence (TADF) material based on a trifluoromethyl pyridine derivative receptor and a preparation method and application thereof. Trifluoromethylpyridine has the advantages of moderate electron absorption performance, easy chemical modification and the like, and is a better semiconductor electronic acceptor unit. The invention provides a novel trifluoromethyl pyridine unit with an electron acceptor structure, and a D-π-A type blue light TADF material is constructed, a phenyl π bridge is connected between the intramolecular donor and acceptor units, and the space between the donor unit HOMO and the acceptor unit LUMO is effectively reduced to be obtained. Small Δ EST , Migration performance between reverse systems is promoted to achieve slave T. 1 To S1 The rapid transition of the state reduces the non-radiative transition of the molecule and improves the luminous efficiency of the material.

Liquid crystal thermal activity delays fluorescent materials and their applications

The present invention belongs to the field of organic electroluminescent material technology, particularly relates to a class of liquid crystal thermal activity delayed fluorescence (TADF) materials and applications, such new liquid crystal thermal activity delayed fluorescent materials to aromatic amine derivatives as donor units, diphenyl sulfone as the acceptor unit, biphenyl derivatives as liquid crystal tints.
