Self-Assembly of Nano- to Macroscopic Metal–Phenolic
Materials
Posted on 2018-08-09 - 19:17
The
self-assembly of molecular building blocks into well-defined
macroscopic materials is desirable for developing emergent functional
materials. However, the self-assembly of molecules into macroscopic
materials remains challenging, in part because of limitations in controlling
the growth and robustness of the materials. Herein, we report the
molecular self-assembly of nano- to macroscopic free-standing materials
through the coordination of metals with natural phenolic molecules.
Our method involves a simple and scalable solution-based template
dipping process in precomplexed metal–phenolic solutions, enabling
the fabrication of free-standing macroscopic materials of customized
architectures (2D and 3D geometries), thickness (about 10 nm to 5
μm), and chemical composition (different metals and phenolic
ligands). Our macroscopic free-standing materials can be physically
folded and unfolded like origami, yet are selectively degradable.
Furthermore, metal nanoparticles can be grown in the macroscopic free-standing
films, indicating their potential for future applications in biotechnology
and catalysis.
