Benchmark Acetylene Binding Affinity and Separation through Induced Fit in a Flexible Hybrid Ultramicroporous Material.

ABSTRACT: Structural changes at the active site of an enzyme induced by binding to a substrate molecule can result in enhanced activity in biological systems. Herein, we report that the new hybrid ultramicroporous material sql-SIFSIX-bpe-Zn exhibits an induced fit binding mechanism when exposed to acetylene, C₂ H₂ . The resulting phase change affords exceptionally strong C₂ H₂ binding that in turn enables highly selective C₂ H₂ /C₂ H₄ and C₂ H₂ /CO₂ separation demonstrated by dynamic breakthrough experiments. sql-SIFSIX-bpe-Zn was observed to exhibit at least four phases: as-synthesised (α); activated (β); and C₂ H₂ induced phases (β' and γ). sql-SIFSIX-bpe-Z
