Embedding void into condensed soft matter

Nature does not like a void. We challenge to introduce a void into condensed phase of soft matter like gels. Recently our group has been developing methods to synthesize porous soft matter. We build up from RhMOPs – these pre-assembled building blocks are stable in solution, and withstand activation processes for gas sorption. They can be linked together using ditopic ligands, and through exploration of assembly pathways we have synthesized coordination polymer particles or self-supporting gels based on these RhMOPs. The porous units remain intact when solvent is removed from the lattice, allowing us to demonstrate that the materials store gas molecules, and opening the door to applications in mass transport and catalysis.

In ongoing work, we are using dynamic, physical methods to trigger the supramolecular assembly of the polymers and investigating how to control the precise spatial distribution of the materials.
