Advanced Optical Materials, EarlyView.Sequential indolo‐fusion π‐extension as a rational design strategy to further narrow the emission bandwidth of multi‐resonance thermally activated delayed fluorescence is introduced. By fusing one or two additional indole moieties to the periphery of Cz‐B, gradual spectra narrowing and accelerated triplet–singlet exciton spin conversion are ...

Hyperphosphorescent OLEDs: Harnessing the Power of MR‐TADF Terminal Emitters
Advanced Optical Materials, EarlyView.Hyperphosphorescent organic light‐emitting diodes (HP‐OLEDs) use phosphorescent sensitizers with multiresonant thermally activated delayed fluorescence terminal emitters. HP‐OLEDs show efficient, narrowband electroluminescence and moderate efficiency roll‐off.

Forbidden dark matter combusted around supermassive black hole
Physics Letters B, 2023 The forbidden dark matter cannot annihilate into a pair of heavier partners, either SM particles or its partners in the dark sector, at the late stage of cosmological evolution by definition.

Highly Efficient Upconverted Fluorescence from Coulombically Assembled Ion Pair
Advanced Optical Materials, EarlyView.A dicationic Os(II) complex paired with two monoanionic fluorophores is designed to enable highly efficient triplet–triplet annihilation upconversion, achieving a remarkable upconverted fluorescence quantum yield of 13% at 785 nm excitation with a record‐low threshold intensity of 5.9 mW cm⁻2, attributed to diffusion‐free acceleration of energy ...
