Interpenetrated In(III)-MOF with Multiple Recognition Sites for Single-Step Ethylene Purification.

An interpenetrated indium(III) metal-organic framework (MOF), , with a rarely reported tetrameric indium cluster is developed for streamlining ethylene purification from C2 gases. At 298 K, the adsorption capacities exhibited a complete reversal sequence of CH > CH > CH. Grand canonical Monte Carlo simulation indicated that the corners in a octahedral cage facilitated the CH/CH separation, while the pocket-like aperture situated between adjacent octahedral cages allows for full contact of CH. Breakthrough experiments illustrated that could yield pure CH in a single step with a productivity of 0.42 mmol g.
