A microporous metal–organic framework with both open metal and Lewis basic pyridyl sites for highly selective C2H2/CH4and C2H2/CO2gas separation at room temperature
Abstract
To immobilize both open metal and Lewis basic pyridyl sites into a microporous metal–organic framework, Cu6(PDC)6·2.6H2O (UTSA-50) was solvothermally synthesized and characterized. The combination of open metal sites and Lewis basic pyridyl functional sites leads to a high acetylene adsorption enthalpy of 39.4 kJ mol−1. As a result, UTSA-50 is a very promising MOF material for the highly selective separation of C2H2/CH4 and C2H2/CO2 at room temperature with the highest C2H2/CH4 separation selectivity of 68 ever reported and moderately high acetylene uptake of 91 cm−1 g−1.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
