Recent advances and prospects for high‐efficiency blue hot exciton organic light‐emitting diodes
FlexMat, EarlyView.Blue organic light‐emitting diodes (OLEDs) face great challenges in achieving the balance between color purity, device efficiency, and stability. Hot exciton materials offer a solution by rapidly converting non‐emissive triplet excitons into singlet ones through a high‐lying reverse intersystem crossing process.

Hydrogen Bonding Denticity Governs Surface Modulation in Inorganic Perovskite Nanocrystals
Small, EarlyView.Organic cations with distinct hydrogen‐bonding denticities enable systematic modulation of perovskite nanocrystal surfaces. Increasing denticity from mono‐dentate MA+ to bi‐dentate FA+ and multi‐dentate GA+ strengthens interactions with surface iodides, effectively suppressing surface defects.
