Photo‐Switching Thermal and Lithium‐Ion Conductivity in Azobenzene Polymers
Advanced Functional Materials, EarlyView.Light‐responsive azobenzene polymers control thermal and ionic transport simultaneously through structural transitions. UV illumination disrupts π–π stacking, converting crystalline trans states to amorphous cis configurations. Thermal conductivity drops from 0.45 to 0.15 W·m−1·K−1 while Li+ diffusivity increases 100 fold. This dual transport switching
