Understanding Interfacial Photoswitching Mechanisms in Atomically‐Thin TMD‐Spiropyran Hybrids

Advanced Materials Technologies, EarlyView.
Photochromic molecules can effectively modulate the optoelectronic properties of atomically thin transition metal dichalcogenide semiconductors. Spiropyran that switches its chemical configuration upon alternating UV and visible irradiation enables light‐programmable optoelectronic devices.

Turning Water Into a Tool: From Degradation Pathways to Functional Engineering in Halide Perovskites

Advanced Materials Technologies, EarlyView.
Water exhibits a threshold‐dependent dual role in lead halide perovskites, acting either as a degradation trigger or as a powerful tool for defect passivation, recrystallization, and structural engineering. This review discusses how controlled water‐mediated interactions govern stability, dimensionality, and optoelectronic performance, providing ...

Lead‐Free Chiral Hybrid Metal Halides for Circularly Polarized Light‐Emitting Diodes

Advanced Optical Materials, EarlyView.
Lead‐free chiral hybrid metal halides provide a versatile platform for realizing chiroptical responses through chiral modulation of metal–halide frameworks with diverse dimensionalities, induces inversion‐symmetry breaking and enables dissymmetric excited‐state transitions toward efficient circularly polarized luminescence and electroluminescence.

Benzo[b]Thiophene‐Derived Low‐T1 Multi‐Resonance Emitter with Suppressed Thermally Activated Delayed Fluorescence for Extending Organic Light‐Emitting Diode Lifetime by Managing Triplet‐Related Bimolecular Interactions

Advanced Optical Materials, EarlyView.
Introducing a 5‐phenylbenzo[b]thiophene unit into the DABNA core lowers the T1 level, enlarging the ΔEST to suppress TADF. This molecular design preserves narrow deep‐blue emission while drastically reducing triplet‐related degradation. Consequently, the resulting emitter, BN‐TPh‐TPA, delivers a threefold operational lifetime over the TADF‐active t ...
