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 ...

Bioinspired, Rapidly Responsive Magnetically Tunable Stiffness Metamaterials

Advanced Materials, EarlyView.
A 3D array of magnetoactive mechanical metamaterials enables rapid and reversible stiffness modulation under external magnetic fields. By adjusting field direction and intensity, the system exhibits diverse deformation modes and tunable modulus. This fast‐responding mechanical metamaterial offers real‐time adaptability for advanced reconfigurable and ...

Accompanying Structural Transformations in Polarity Switching of Heavily Doped Conjugated Polymers

Advanced Materials, EarlyView.
The polarity switching of heavily doped p‐type conjugated polymers (CPs) toward environmentally stable electron‐rich thin films is demonstrated. Multiscale analyses, incorporating spectroscopic, electrochemical, and scattering techniques, reveal structural and chemical transformations induced by excessive doping with AuCl3.

Nickel Hydroxide Catalyzed Bias‐free Photoelectrochemical NH3 Production via Nitrate Reduction

Advanced Materials, EarlyView.
A bias‐free photoelectrochemical nitrate reduction reaction with high efficiency and production rate is achieved using a crystalline silicon photocathode with nickel as the catalyst. Performing the PEC NO3RR under alkaline conditions can be self‐activated of the Ni surface by forming Ni(OH)2.

Polycondensation as a Universal Method for Preparing High‐Density Single‐Atom Catalyst Libraries

Advanced Materials, EarlyView.
This paper presents a universal bottom‐up polycondensation strategy for synthesizing high‐density single‐atom catalysts (HD‐SACs) with metal loadings up to 27.5 wt%. Using various metal monomers with 1,10‐phenanthroline‐5,6‐dione ligands, it generates atomically dispersed mono‐ and bimetallic HD‐SACs.
