Description
Christophe Lavenn leads a 2026 team unlocking hidden flex in a soft porous crystal with one small ligand swap. Flexible frameworks can gulp gas in sudden steps, prized for storage, yet design rules for that flex stay murky. Swapping a benzene based linker for a pyridine cousin added a nitrogen that welcomes hydrogen bonds from acetylene gas. The change woke dormant flex in the lattice.
Pore volume swelled by nearly threefold under gas, and acetylene uptake rose five times over the parent material. Uptake also climbed in distinct steps and favored acetylene over close cousins ethylene and ethane. Lavenn and the team credit hydrogen bonding for steadying the open form, and offer the swap as a general design hint.
