Breathing in metal-organic frameworks (MOFs), the distinctive transformation {between|in between|among|amongst|involving} a porous phase {and a|along with a|as well as a|plus a|and also a|in addition to a} {less|much less|significantly less} (or non) porous phase, {often|frequently|usually|typically|generally|normally} controls the uptake of guest molecules, endowing {flexible|versatile} MOFs with {highly|extremely|very|hugely} selective gas adsorptive properties. In {highly|extremely|very|hugely} {flexible|versatile} topologies, breathing behaviour {can be|may be|could be|might be|is often|is usually} tuned by linker modification, {which is|that is|which can be} {typically|usually|normally|generally|commonly|ordinarily} {achieved|accomplished} pre-synthetically by {the use of|the usage of} functionalised linkers. Herein, we show that MIL-88A(Sc) exhibits the characteristic flexibility of its topology, which {can be|may be|could be|might be|is often|is usually} tuned by (i) modifying synthetic {conditions|circumstances|situations} to yield a formate-buttressed analogue {that is|that’s|which is|that is certainly|that is definitely|that may be} rigid and porous, and (ii) postsynthetic bromination across the alkene functionality {of the|from the|in the|on the|with the|of your} fumarate ligand, {generating|producing|creating} a {product|item|solution} {that is|that’s|which is|that is certainly|that is definitely|that may be} rigid but non-porous. {As well as|In addition to|Along with|And also|Together with|And} {providing|supplying|offering|delivering|giving} {different|various|distinct|diverse|unique|distinctive} methodologies for tuning the flexibility and breathing behaviour of this archetypal MOF, we show that bromination {of the|from the|in the|on the|with the|of your} formate-bridged analogue {results|outcomes|final results|benefits} in an identical material, representing a {rare|uncommon} {example|instance} of two {different|various|distinct|diverse|unique|distinctive} MOFs {being|becoming|getting} postsynthetically converted {to the|towards the|for the} {same|exact same|identical|very same|similar} {end|finish} {product|item|solution}.
