Polymer Metal-Organic Cage Gels Based on Cu24L24 Cuboctahedra: Design, Synthesis, and Additive Manufacturing Enabled by Three-State Photoswitching

This manuscript presents a novel polyMOC network that can reversibly switch between three distinct states of mechanical and chemical properties, significantly extending the boundaries of stimuli-responsive materials. This triple switching phenomenon is enabled by a unique photoreduction mechanism that leverages Cu24L24 self-assembled metal-organic cages (MOCs) embedded in an elastic polymer gel. The properties of each material state can be used in a cooperative fashion to achieve advanced functions such as network toughening, metallic patterning, and additive manufacturing
