Reprogrammable 4D Printed Liquid Crystal Elastomer Photoactuators by Means of Light‐Reversible Perylene Diimide Radicals (Adv. Funct. Mater. 9/2024)

Abstract

Liquid Crystal Elastomer Photoactuators In article number 2309019, Carlos Sánchez-Somolinos and co-workers introduce 4D printing of liquid crystal elastomers with green-absorbing perylene diimide chromophores. Green light irradiation of the elastomer generates far-red absorption bands associated with photogenerated radical species. This allows spatial reconfiguration of the material to far-red light, enabling intricate morphing capabilities with interest in biomedical and soft robotic applications.
