High‐Performance Phototransistor Based on a 2D Polybenzimidazole Polymer

Advanced Materials, EarlyView.
A crystalline 2D polybenzimidazole polymer (2DPBI), incorporating a porphyrin‐based π‐system linked via 1,3‐diazole units, is synthesized on the water surface over large areas. The 2DPBI thin‐film exhibits high charge carrier mobility (≈240 cm2 V−1 s−1, measured by terahertz spectroscopy), strong photoresponse, and band‐like transport, enabling ...

Molecular Nanoarchitectonic Sensing Layer for Analysis of Volatile Fatty Acids in Bioreactor Headspaces Using a Nanomechanical Sensor

Advanced Materials Technologies, EarlyView.
A porous crystalline sensing layer has been developed in conjunction with a nanomechanical sensor for the sensitive detection of volatile fatty acids (VFAs) in admixture at high relative humidity. The sensitive, selective sensor based on supramolecular design improves the economic viability of anaerobic digesters toward a carbon neutral society ...

Influence of Outcoupling Layers on Top‐Emitting Perovskite Light‐Emitting Diodes

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Top‐emitting perovskite LEDs offer benefits over typical bottom‐emitting architectures, toward lasing, improved thermal management, and on‐chip fabrication compatibility. Outcoupling layers offer a strategy uniquely applicable to top‐emitting LEDs to optimize EQE by improving optical outcoupling.

Biocatalytic Alkylation of Ambident Nucleophiles Enables Selective N‐Functionalization of Heterocycles and Late‐Stage Modifications

Angewandte Chemie, EarlyView.
N‐alkylated heteroarenes are key structural motifs in bioactive compounds, but their regioselective synthesis via coupling of readily available azoles with haloalkanes remains very challenging. Here, we present a mild biocatalytic approach that proceeds on gram‐scale, is highly chemo‐ and regioselective, offering rapid access to valuable N‐alkylated ...

Isotope Engineering of Tetraphenylethylene: Aggregate‐Dependent Enhancement of Luminescence Efficiency

Angewandte Chemie, EarlyView.
In loosely packed nanoaggregates, increased deuteration enhances photoluminescence quantum yields (PLQY) and extends the fluorescence lifetimes of tetraphenylethylene (TPE) by reducing internal conversion rates. Conversely, in tightly packed crystalline states, deuteration leads to decreased PLQY and shortened lifetimes, attributable to the Duschinsky ...

Boosting Organic Long Persistent Luminescence by Enhancing Charge Separation Processes in Three‐Component Systems

Advanced Science, EarlyView.
Electron donor TMB is introduced into BF2bdk‐PhB system to enhance charge separation process. The resultant three‐component materials exhibit visible‐light‐excitable OLPL afterglow lasting for several hours under ambient environment, with OLPL efficiency of ≈10% and display OLPL brightness comparable to inorganic materials.
