abstract = {The mechanical robustness of MOFs is crucial in most
adsorption-related applications. Herein, we investigated the
interaction of the mesoporous metal–organic framework
DUT-76(Cu) with various C1–C4 hydrocarbons at their
boiling points. During adsorption, the pore structure
partially collapsed into an amorphous phase while retaining
a residual porosity. We employed a combination of multicycle
physisorption experiments using different hydrocarbons
(methane, ethane, ethylene, propane, propylene, n-butane,
and 1,3-butadiene) along with X-ray diffraction, scanning
electron microscopy, and total scattering to examine this
transition. This methodology allowed us to gain a
comprehensive understanding of the effects on the crystal
structure, local structure, and macroscopic behavior of the
material. Furthermore, we identified specific correlations
among the chain length, number of double bonds, and
adsorption/desorption cycle stability, which are influenced
by adsorption-induced stress. These multicycle adsorption
experiments served as semiquantitative tools for assessing
the mechanical stability of mesoporous frameworks.},
