Non‐Contact, Non‐Contamination, and High‐Resolution Electrostatic Imaging with Floating‐Extended‐Gate Organic Field‐Effect Transistors

open access: yesAdvanced Materials Technologies, EarlyView.
Invisible static electricity poses serious industrial risks such as electronics failures and fire accidents. Detecting it is particularly challenging when positive and negative charges are densely mixed. Flexible and printed organic transistor sensors can visualize these hidden charge patterns on plastic surfaces.

Event‐Driven Elongation Monitor for Soft Devices Using a Deformation‐Activated Piezoconductive Switch

open access: yesAdvanced Materials Technologies, EarlyView.
A stretchable, event‐driven strain sensor with low energy consumption is developed using positive piezoconductive composites. These composites remain insulative when relaxed, while they become conductive when stretched. Their electrical characteristics are modifiable by the nickel's weight ratio and cross‐sectional geometry. Strain‐induced switching is

Simultaneous Emission Spectral Narrowing and Spin‐Flip Acceleration in Multi‐Resonance Organoboron Emitters via Sequential Indolo‐Fusion π‐Extension

open access: yesAdvanced 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 ...

Drastic Mechanochromic Luminescence Through Fluorescence–Phosphorescence Switching in a Heavy‐Atom‐Free Organoboron Compound

open access: yesAdvanced Optical Materials, EarlyView.
A new heavy‐atom‐free, donor–acceptor‐type organoboron luminophore has been synthesized, which exhibits red room‐temperature phosphorescence (RTP) in the crystalline state. Furthermore, the amorphous solid generated by grinding shows green thermally activated delayed fluorescence (TADF), displaying distinct mechanochromic luminescence (MCL) through ...
