Foundry Users have created the first 2D supramolecular organic framework (SOF) with honeycomb periodicity using a novel solution-based self-assembly approach.
Significance and Impact
Highly ordered and tunable SOFs lead to new layer-by-layer routes to the synthesis of complex architectures, with potential applications in gas purification, absorption, separation, sensing, and catalysis.
- A cross-linked 2D framework is assembled in water by joining triangular aromatic units with the macrocycle Cucurbituril through non-covalent interactions.
- The framework remains soluble in a single-layer form due to specific built-in steric groups that prevent inter-layer stacking.
- Single-layer 2D networks provide precise dimension control of resulting structures, which facilitates structural and chemical customization.
