Conjugation Pathway of Benzobisoxazoles in Polymer Donors Mediates the Charge Management and Enables Organic Solar Cells with Record Certified Efficiency

Advanced Materials, EarlyView.
Herein, the conjugation pathway isomerism of the benzobisoxazole (BBO) building block is systematically compared, by which a certified efficiency of 19.1% is obtained in corresponding all‐polymer solar cells. Abstract Charge management plays a pivotal role in achieving high‐performance bulk heterojunction (BHJ) organic solar cells (OSCs). In this study,

Active Fabric Origami Enabled by Digital Embroidery of Magnetic Yarns

Advanced Materials, EarlyView.
This study demonstrates a scalable textile manufacturing process that fabricates active origami fabrics (AFO) via digital embroidery of magnetic yarns. The programmable AFO exhibits reversible 2D and 3D transformations under magnetic fields, enabling functionalities such as altering surface roughness and linear actuation.

Spin‐State Manipulation of Atomic Manganese Center by Phosphide‐Support Interactions for Enhanced Oxygen Reduction

Advanced Materials, EarlyView.
The electronic configuration of Mn single‐atom sites is regulated from low‐spin to high‐spin states by embedding well‐defined molybdenum phosphide nanocrystals nearby (MoP@MnSAC‐NC). The electronic phosphide‐support interaction between MoP and Mn single atoms drives the electronic structure transition in Mn sites from low‐spin to high‐spin states, and ...

Synthetic Chromatophores for Color and Pattern Morphing Skins

Advanced Materials, EarlyView.
Cephalopods use chromatophore organs (muscle‐actuated pigment sacs) to alter their skin color and pattern. Synthetic chromatophores, which closely mimic the mechano‐optical process found in cephalopods using stimuli‐responsive microscale hydrogel actuators, are reported.
