Step by step
- The IRMOF seriesMOF-5 was functionalized with –Br, –NH₂, –OC₃H₇, –OC₅H₁₁, –C₂H₄ and –C₄H₄ and expanded with biphenyl, tetrahydropyrene, pyrene and terphenyl struts: an isoreticular series, one with the same framework topology, of 16 highly crystalline materials with pores from 3.8 to 28.8 Å and open space up to 91.1% of the crystal volume (Eddaoudi 2002). IRMOF-1 is MOF-5 (Boyd 2017); IRMOF-8 is Zn₄O(ndc)₃ (Feldblyum 2012); IRMOF-10 is the non-interpenetrated Zn₄O(BPDC)₃ (Wang 2014); IRMOF-16, Zn₄O(TPDC)₃, has pores up to 28.8 Å (Kalmutzki 2018)
- IRMOF-74-I to -XIExpanding the link of MOF-74 from one phenylene ring (I) to two to seven, nine and eleven (II to XI) gave IRMOF-74-I to -XI, with pore apertures from 14 to 98 Å; all are noninterpenetrated and stable up to 300 °C, and the apertures of oligoethylene glycol-functionalized IRMOF-74-VII and -IX are large enough for natural proteins to enter the pores (Deng 2012). IRMOF-74-XI has 85 × 98 Å pores, the largest 1D pores in MOFs reported by 2018 (Kalmutzki 2018)
- HKUST-1 to MOF-399MOF-399, Cu₃(BBC)₂ on the tbo net, has a unit cell volume 17 times that of the first reported material isoreticular to it, 94% porosity and a density of 0.126 g cm⁻³ (Furukawa 2011); BBC is 4,4′,4″-[benzene-1,3,5-triyl-tris(benzene-4,1-diyl)]tribenzoate (Furukawa 2010). ZJU-35 and ZJU-36 have the same tbo topology as HKUST-1, with pores of 14.4 and 16.5 Å against 10.8 Å in HKUST-1 (Kong 2013); HKUST-1 joins [Cu₂(O₂CR)₄] units by benzene-1,3,5-tricarboxylate (Chui 1999)
- IRMOF-9 or IRMOF-10Zn₄O(BPDC)₃ forms interpenetrated IRMOF-9 or non-interpenetrated IRMOF-10 (Wang 2014). Independent nets interpenetrate in many polymeric, hydrogen-bonded and coordination structures (Batten & Robson 1998); interpenetration greatly reduces the pore size and the available space in a MOF (Shekhah 2009), and catenation diminishes porosity (Farha 2010). IRMOF-8 typically shows only 1000–2000 m² g⁻¹ where more than 4000 m² g⁻¹ is expected, from near-complete interpenetration (Feldblyum 2013). In simulations, catenated MOFs were more selective for CO₂ over CH₄ than their non-catenated counterparts (Babarao 2009)
- Preventing or using itThe steric bulk of a doped linker switched IRMOF-9 to IRMOF-10 (Wang 2014); strut-impervious scaffolds give noncatenated MOFs (Farha 2010). Room-temperature synthesis suppressed interpenetration in IRMOF-8 (Feldblyum 2012); higher temperatures and concentrations favour it (Zhang 2009); liquid-phase epitaxy on an organic template suppressed the second framework (Shekhah 2009). Interpenetration in PCN-6 can lead to higher hydrogen uptake (Zhao 2011); MOF-14, Cu₃(BTB)₂, is a pair of interwoven frameworks that reinforce each other, with pores 16.4 Å across (Chen 2001)
- Multivariate MOF-518 MTV-MOF-5 structures were made from BDC and eight of its derivatives, with up to eight distinct functionalities in one phase; the backbone is ordered but the distribution of the functional groups is disordered, and MTV-MOF-5-EHI is up to 400% more selective for CO₂ over CO than its best same-link counterparts (Deng 2010). Solid-state NMR with simulations told apart random, alternating and cluster apportionments of the groups (Kong 2013). Mixing –H, –NH₂ and –C₄H₄ on BTB helped bring in –NO₂, and multivariate MOF-177 took up 25% more hydrogen (Zhang 2015). With mixed metals, porphyrin MOFs with well-mixed SBUs performed better than the sum of their parts in a photo-oxidation (Liu 2016); MOF-74 took up to ten kinds of divalent metal in one crystal (Wang 2014)
Strengths
- IRMOF-74-VII and -IX have apertures large enough for natural proteins (Deng 2012)
- MOF-14’s interwoven frameworks reinforce each other (Chen 2001)
- Catenated MOFs were more selective for CO₂ over CH₄ in simulations (Babarao 2009)
Limitations
- In the Zn₄O-based IRMOF series, accessible porosity is often limited by interpenetration or by pore collapse when guests are removed (Feldblyum 2013)
- Interpenetration greatly reduces the pore size and the available space (Shekhah 2009)
- In MTV-MOF-5 the distribution of the functional groups is disordered (Deng 2010)

What are the steps shown in “Isoreticular expansion, interpenetration, MTV MOFs”?
1. The IRMOF series: MOF-5 was functionalized with –Br, –NH₂, –OC₃H₇, –OC₅H₁₁, –C₂H₄ and –C₄H₄ and expanded with biphenyl, tetrahydropyrene, pyrene and terphenyl struts: an isoreticular series, one with the same framework topology, of 16 highly crystalline materials with pores from 3.8 to 28.8 Å and open space up to 91.1% of the crystal volume (Eddaoudi 2002). IRMOF-1 is MOF-5 (Boyd 2017); IRMOF-8 is Zn₄O(ndc)₃ (Feldblyum 2012); IRMOF-10 is the non-interpenetrated Zn₄O(BPDC)₃ (Wang 2014); IRMOF-16, Zn₄O(TPDC)₃, has pores up to 28.8 Å (Kalmutzki 2018). 2. IRMOF-74-I to -XI: Expanding the link of MOF-74 from one phenylene ring (I) to two to seven, nine and eleven (II to XI) gave IRMOF-74-I to -XI, with pore apertures from 14 to 98 Å; all are noninterpenetrated and stable up to 300 °C, and the apertures of oligoethylene glycol-functionalized IRMOF-74-VII and -IX are large enough for natural proteins to enter the pores (Deng 2012). IRMOF-74-XI has 85 × 98 Å pores, the largest 1D pores in MOFs reported by 2018 (Kalmutzki 2018). 3. HKUST-1 to MOF-399: MOF-399, Cu₃(BBC)₂ on the tbo net, has a unit cell volume 17 times that of the first reported material isoreticular to it, 94% porosity and a density of 0.126 g cm⁻³ (Furukawa 2011); BBC is 4,4′,4″-[benzene-1,3,5-triyl-tris(benzene-4,1-diyl)]tribenzoate (Furukawa 2010). ZJU-35 and ZJU-36 have the same tbo topology as HKUST-1, with pores of 14.4 and 16.5 Å against 10.8 Å in HKUST-1 (Kong 2013); HKUST-1 joins [Cu₂(O₂CR)₄] units by benzene-1,3,5-tricarboxylate (Chui 1999). 4. IRMOF-9 or IRMOF-10: Zn₄O(BPDC)₃ forms interpenetrated IRMOF-9 or non-interpenetrated IRMOF-10 (Wang 2014). Independent nets interpenetrate in many polymeric, hydrogen-bonded and coordination structures (Batten & Robson 1998); interpenetration greatly reduces the pore size and the available space in a MOF (Shekhah 2009), and catenation diminishes porosity (Farha 2010).

Room-temperature synthesis suppressed interpenetration in IRMOF-8 (Feldblyum 2012); higher temperatures and concentrations favour it (Zhang 2009); liquid-phase epitaxy on an organic template suppressed the second framework (Shekhah 2009). Interpenetration in PCN-6 can lead to higher hydrogen uptake (Zhao 2011); MOF-14, Cu₃(BTB)₂, is a pair of interwoven frameworks that reinforce each other, with pores 16.4 Å across (Chen 2001). 6. Multivariate MOF-5: 18 MTV-MOF-5 structures were made from BDC and eight of its derivatives, with up to eight distinct functionalities in one phase; the backbone is ordered but the distribution of the functional groups is disordered, and MTV-MOF-5-EHI is up to 400% more selective for CO₂ over CO than its best same-link counterparts (Deng 2010). Solid-state NMR with simulations told apart random, alternating and cluster apportionments of the groups (Kong 2013).
