Aggregation‐Induced Emission with Long‐Lived Room‐Temperature Phosphorescence from Methylene‐Linked Organic Donor–Acceptor Structures
Open accessAbstract
Aggregation‐caused quenching (ACQ), where excited‐state and/or ground‐state electronic structures are altered to exhibit an increased proclivity for non‐radiative decay for the aggregates, is largely responsible for the lack of fluorescence and phosphorescence in molecular solids in general. Here we show that ACQ could be effectively circumvented by constructing an aromatic system with a methylene‐linker, where the system exhibits typical aggregation‐induced emission (AIE) with long‐lived room‐temperature phosphorescence, since the tetrahedral structure in the solid state may significantly reduce strong intermolecular interactions contributing to ACQ.

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.
