Abstract

Closed-to-open structural transformations in flexible coordination networks are of potential utility in gas storage and separation. Herein, we report the first example of a flexible SiF-pillared square grid material, [Cu(SiF)(L)] (L = 1,4-bis(1-imidazolyl)benzene), . exhibits reversible switching between nonporous () and several porous (, , , and ) phases triggered by exposure to N, CO, or HO. In addition, heating to 433 K resulted in irreversible transformation to a closed polymorph, . Single-crystal X-ray diffraction studies revealed that the phase transformations are enabled by rotation and geometrical contortion of L. Density functional theory calculations indicated that L exhibits a low barrier to rotation (as low as 8 kJmol) and a rather flat energy surface. In situ neutron powder diffraction studies provided further insight into these sorbate-induced phase changes. combines stability in water for over a year, high CO uptake (ca. 216 cm/g at 195 K), and good thermal stability.
