Synergistic Photomagnetic and Photomechanical Dynamics in a Dysprosium-Based Smart Molecule.

ABSTRACT: Converging photomagnetic switching and photomechanical functionalities in molecular materials is critical for next-generation adaptive technologies, yet challenged by competing demands for rigid coordination environments to suppress quantum tunneling in single-molecule magnets (SMMs) and flexible frameworks to enable macroscopic motion. Herein, photoactive 9-anthracenecarboxylic acid (HAC) is integrated into a binuclear dysprosium(III) complex, (1), which simultaneously exhibits dual light-responsive behaviors of both SMMs and macroscopic mechanical motion. The 365 nm light irradiation induces [4+4] photocycloaddition of anthracene units in 1, driving a single-crystal-to-single-crystal transformation to a 1D coordination polymer [Dy₂(HAC)₂(DMF)₂(AC)₆]n (1A).
