Dynamic supramolecular fluids containing azobenzene tailor sodium-based metal organic frameworks into helical and flower morphology

Multiphasic structuring has emerged as a transformative strategy for controlling self-assembly at the nanoscale, enabling the creation of materials with unprecedented complexity and functionality. By introducing azobenzene-based supramolecular fluids into solvothermal reactions, we direct the formation of intricate metal-organic framework (MOF) superstructures with unique morphologies, such as bouquet and flower-like architectures. These superstructures exhibit emergent behaviors, including chirality transformations and structural adaptations, mimicking life-like dynamics observed in natural systems. Our approach leverages the interplay of molecular design and phase behavior to achieve precise control over morphological evolution within hermetic environments, offering a new perspective on MOF synthesis. These findings expand the horizons of material design, paving the way for the development of adaptive and biomimetic systems with unparalleled precision and functionality.
