Gel‐Gel Interface Engineering for the Synthesis of Anisotropic Hydrogels with Designable Polymer Orientations

Advanced Materials, EarlyView.
This study reports that when a gel‐gel interface is intentionally introduced into a hydrogel via two‐step polymerization, the polymer networks near the interface spontaneously align perpendicular to it. By employing a photo‐initiator system to spatially control the gel‐gel interface, anisotropic hydrogels with programmable orientations of polymer ...

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 ...

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.

Fluoroether Design Enables High‐Voltage All‐Solid‐State Lithium Metal Batteries

Advanced Materials, EarlyView.
A durable high‐voltage all‐solid‐state electrolyte is developed by incorporating a novel organic/inorganic hybrid porous component with a fluoroether design. Due to the weakened Li+ coordination structure, the proposed high‐voltage SSE exhibits durable antioxidation.

Carbazole‐Based Thin Microporous Polymer Films for Photocatalytic Hydrogen Evolution

Advanced Materials, EarlyView.
Photocatalytic hydrogen evolution with electropolymerized microporous films enable a direct and scalable process for the production of industrial relevant amounts of hydrogen gas. For developing cost‐ and material‐effective devices it is beneficial to increase the accessible outer surface area via microstructuring and stacking of polymeric films ...

A Light‐Driven Closed‐Loop Chemical Recycling System for Polypinacols

Advanced Materials, EarlyView.
This study presents a novel strategy for the photochemical closed‐loop recycling of hydroxyl‐rich polymers. Simple bis‐aldehyde precursors are employed to synthesize polypinacols via UV light irradiation. Subsequent depolymerization is achieved under visible light using a cerium‐based photocatalyst, enabling monomer recovery through selective cleavage ...
