“…13,19 While this anomalous behavior could be benecial for the development of zero-expansion composites for highly-specialized applications, 20 it poses some additional design constraints when in contact with conventional materials. Various practical ways of controlling the thermal expansion behavior of MOFs have already experimentally been demonstrated: retrotting, 21 adsorption of guest molecules, 17,22,23 changing the organic linkers or metal ions, 17,24,25 adding functional groups, 16 incorporating defects, 26 etc. Computational studies corroborate these ndings.…”
