An In Situ Study of the Topochemical Transformation of Hybrid Layered Hydroxides Into Metallic Nanocomposites

Advanced Functional Materials, EarlyView.
Herein, the topochemical transformation of cobalt‐based layered hydroxides into nanocomposites is investigated using advanced real‐time characterization techniques combined with thermogravimetric analysis. The study reveals how interlayer carboxylic acids direct the transformation pathway, highlighting the role of carbon content and anion length. These

The Dynamics of Interfacial Trap States in High‐Detectivity Near‐Infrared Photomultiplication Organic Photodetectors

Advanced Functional Materials, EarlyView.
Photomultiplication organic photodetectors (PM OPDs) are an attractive strategy for health‐monitoring. Here, PM‐OPDs are reported with a specific detectivity of 5.7 × 1012 Jones and external quantum efficiency values of 3500% under −10 V. The dynamics of carrier trapping in these devices are elucidated through trap selective spectroscopical techniques.

Unusual Swelling Behavior of Hydrogels Modified with Spiropyran as Appendage or Crosslinker

Advanced Functional Materials, EarlyView.
Not so innocent after all—spiropyran crosslinkers in methylenebisacrylamide‐crosslinked poly(acrylamide‐co‐acrylic acid) hydrogels increase crosslinking density, but also, counterintuitively, increase swelling. Charge complexation, cooperative chemo‐mechanical effects, and aggregation may explain these observations.

Droplet Triboelectrification on Liquid‐Like Polymer Brushes

Advanced Functional Materials, EarlyView.
This work investigates the triboelectrification of water droplets on polymer brush‐coated surfaces exhibiting minimal contact line pinning. Such surfaces enable the systematic study of electrode patterning and controlled changes in droplet contact area.

Anomalous Stiffening of a Conjugated Polymer During Electrochemical Oxidation

Advanced Functional Materials, EarlyView.
The electromechanical response of a thienothiophene‐based conjugated polymer with triethylene glycol side chains is investigated. Electrochemical nanoindentation and atomic force microscopy reveal a modest and reversible increase in elastic modulus at room temperature upon electrochemical oxidation.
