porosities and functional properties are extremely rare due to weak hydrogen-bonding interactions among molecular organic
linkers which are much more fragile and difficult to stabilize. Herein, through judiciously combining the superiority of
both the moderately stable coordination bonds in MOFs and hydrogen bonds, we have realized a microporous hydrogenbonded
metal-complex or metallotecton framework HOF-21, which not only shows permanent porosity but also exhibits
highly selective separation performance of C2H2/C2H4 at room temperature. The outstanding separation performance can be
ascribed to sieving effect confined by the fine-tuning pores and the superimposed hydrogen-bonding interaction between
C2H2 and SiF62- on both ends as validated by both modeling and neutron powder diffraction experiments. More importantly,
the collapsed HOF-21 can be restored by simply immersing it into water or salt solution. To the best of our knowledge, such
extraordinary water stability and restorability of HOF-21 was observed for the first time in HOFs, underlying the bright perspective
of such new HOF materials for their industrial usage.
