Abstract
AbstractBioinspired molecular and macromolecular systems could be a driver for new generation semiconductor‐synthetic biology (Semi‐Syn‐Bio) technologies, shifting the materials design paradigm by utilizing bioinspired and biological structures to design molecular and supramolecular architectures as bionanomaterials in the fabrication of devices and components. Herein, a simple and rapid self‐assembly approach of interfacial coordination programming of a biological amphiphile, a fatty acid, using a transition metal ion, copper cation (Cu2+) to direct the formation of nanoflowers of Cu2+‐conjugated supramolecular structures is demonstrated. The fatty acid molecules form complexes with the copper ions and then self‐assemble into microstructures with flower‐like petals, which are highly nanoporous thin sheets. The growth of microstructures is found to be independent from the precursors’ stoichiometric ratios, demonstrating a versatile interfacial coordination programming approach to make crystalline, uniquely shaped‐double peony flower‐like microstructures. It is anticipated that design principles and directed self‐assembly approaches for the interfacial coordination programming of biomolecules may advance the state‐of‐the‐art of biomaterials research, providing deeper understanding in the paradigm of design, synthesis, self‐assembly, and fabrication of Semi‐Syn‐Bio superstructure systems.
