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

open access: yesAdvanced 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 ...

Omnidirectional Ultra‐Broadband Cu/TiO2 Metasurface Absorbers for High‐Efficiency Solar Thermal Conversion and Photothermal Plasmon‐Driven Catalysis

open access: yesAdvanced Optical Materials, EarlyView.
Metasurface shows selective solar–thermal energy conversion with high‐activity solar/laser‐driven chemistry. The breakthrough is co‐designing broadband FP‐cavity + plasmonic LSPR/SLR resonances in an ultra‐thin metamaterial so that it not only harvests the most efficient proportion of solar radiation but also suppresses mid and IR emissivity. Moreover,

New High‐Tc Charge‐Transfer Multiferroicity in the Quasi‐2D Antiferromagnet CrSbS3

open access: yesAdvanced Science, EarlyView.
ABSTRACT Low‐dimensional magnets, particularly 2D systems, offer a rich platform for realizing unconventional multiferroic mechanisms, especially when multiple polarization channels coexist. In the quasi‐2D antiferromagnet CrSbS3, which crystallizes in the centrosymmetric orthorhombic space group Pnma and orders magnetically at TN ≈ 90 K, two ...
