Robust Luminescent Materials with Prominent Aggregation-Induced Emission and Thermally Activated Delayed Fluorescence for High-Performance Organic Light-Emitting Diodes
Abstract
Abstract Aggregation-induced emission (AIE) materials have excellent solid-state emission by suppressing concentration quenching and exciton annihilation, while thermally activated delayed fluorescence (TADF) materials are able to fully utilize electrogenerated singlet and triplet excitons. The collaboration of AIE and TADF should be a rational strategy to design novel robust luminescent materials. Herein, two new materials with both prominent AIE and TADF properties are developed based on a central benzoyl acceptor core and different donor units. Their crystal and electronic structures, thermal stabilities, photophysical properties, and energy levels are investigated systematically. The doped organic light-emitting diodes (OLEDs) based on them show green lights and perform outstandingly, providing excellent electroluminescence (EL) efficiencies of up to 19.2%, 60.6 cd A–1, and 59.2 lm W–1. Their nondoped OLEDs are turned on at very low turn-on voltages (2.7 V) and afford yellow lights and high EL efficiencies of 9.7%, 26.5 cd A–1, and 29.1 lm W–1, with low efficiency roll-off. These results actually demonstrate the feasibility to explore new efficient emitters by the marriage of AIE and TADF.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
