Printed SWCNT‐Based p–n Junction Thin‐Film Near‐Infrared Photoresistors Enabled by a Sustainable Furan‐Derived π‐Conjugated Polymer

Advanced Materials Technologies, EarlyView.
A sustainable polymer–carbon nanotube bilayer enables efficient near‐infrared photodetection in a simple lateral planar p–n junction thin‐film architecture. Thermal side‐chain cleavage enhances interfacial coupling, shifts the dominant photoresponse from 800 to 1000 nm, and substantially improves device performance.

The Role of Charge Transfer and Linker States in the Magnetoluminescence of a Diradical With Two Spatially Proximate Triarylmethyl Units

Advanced Optical Materials, EarlyView.
Magnetoluminescent (ML) diradicals exhibit field‐dependent emission due to magnetic field‐dependent spin state populations and spin‐dependent emission properties. In this work, quantum chemical calculations applied to the first reported ML diradical provide evidence of the different deactivation pathways of the excited singlet and triplet states and ...

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 ...
