A metal–organic framework based propylene nano-trap with dual functionalities for highly efficient propylene/propane separation

We have reported a dual functionalized single-molecule nano-trap MOF with both top-tier C 3 H 6 capture capacity and selectivity, affording both remarkably large C 3 H 6 uptake of 2.6 mmol g −1 and high dynamic selectivity of 10 for C 3 H 6 /C 3 H 8 separation.
