Synergistic binding sites in a hybrid ultramicroporous material for one-step ethylene purification from ternary C₂ hydrocarbon mixtures.

ABSTRACT: One-step separation of C₂H₄ from ternary C₂H₂/C₂H₄/C₂H₆ hydrocarbon mixtures is of great significance in the industry but is challenging due to the similar sizes and physical properties of C₂H₂, C₂H₄, and C₂H₆. Here, we report an anion-pillared hybrid ultramicroporous material, CuTiF₆-TPPY, that has the ability of selective recognition of C₂H₄ over C₂H₂ and C₂H₆. The 4,6-connected fsc framework of CuTiF₆-TPPY exhibits semi-cage-like one-dimensional channels sustained by porphyrin rings and TiF₆^2- pillars, which demonstrates
