A two-dimensional reticular triaxial molecularly woven fabric.

A two-dimensional reticular triaxial woven polymer network built from C3-symmetric macrocycles via dative B-N polymerization exhibits unique topological chirality and robust mechanical properties.

• Why it matters: Higher-order (≥3 axes) molecular weaving with nonlinear building blocks is expected to yield new architectures and functions, but constructing and testing such systems remains insufficiently explored.
• What they did: The authors incorporate C3-symmetric macrocycles into a woven polymer network using dative B-N polymerization, then evaluate topology, mechanics, and porous separation performance.
• The result: The material’s porous structure enables separation of representative aromatic/aliphatic compounds, showing that triaxial woven topologies can regulate material properties through an added topological dimension.
