Reticular Chemistry 3.2: Typical Minimal Edge-Transitive Derived and Related Nets for the Design and Synthesis of Metal–Organic Frameworks

Abstract

Reticular chemistry has proven as a notable/distinctive discipline aimed at the deliberate assembly of periodic solids, offering great opportunities to effectively deploy the gained knowledge on net-topologies as a guide and toolbox for designed syntheses, based on the assembly of molecular building blocks into targeted and anticipated structures of crystalline extended solids. The effective practice of reticular chemistry has enriched the repertoire of crystal chemistry and afforded the notable accelerating development of crystalline extended frameworks, especially metal-organic frameworks (MOFs). Here, we review a special class of trinodal MOF structures based on the reticulation of special minimal edgetransitive nets (nets with transitivity [3 2], three distinct nodes and two kind of edges) derived from edge-transitive nets (one kind of edge). The rationale for deriving these special minimal edge-transitive nets is reviewed and their associated net-coded building (net-cBUs) for the design of trinodal MOFs is presented and discussed. The resultant inclusive list of the enumerated minimal edge-transitive nets provides a unique toolbox for the material's designer as it offers ideal blueprints for the deliberate design and rational assembly of building blocks with embedded multiple branch points into intricate trinodal MOFs.

“…Die Suche nach hochgradig vernetzten MOFs regt die Kreativität der Forscher an; wenn eine bestimmte Geometrie nicht im MBB‐Katalog existiert oder erst noch entdeckt werden muss, ist es oft möglich, durch die Verwendung abgeleiteter und verwandter Netzwerke [42] alternative Wege zu finden, um die insgesamt erwartete Topologie zu erreichen.…”

25 Years of Reticular Chemistry

“…In parallel to the fruitful systematic screening of combinations of organic ligands with various metals,itwas evident that ahigher level of prediction in the assembly of MOFs was needed. This is where topology and geometrical consider-ations found their major role.Aside from being an invaluable tool for the description and understanding of MOF structures, [40][41][42] topology,a nd particularly edge-transitive nets, [43] are avaluable asset owing to their design and identification of required geometrical attributes to achieve ag iven net. The first example of this strategy is the synthesis of MOF-101, where the steric hindrance generated by the bromo functionalization of aterephthalic acid forces the adjacent carboxylate to rotate out of plane.…”

“…The most attractive property of MOFs is huge porosity and designable pores [24] . Compared with other conventional porous materials, MOFs have very high porosity (for example, NU‐110E has Brunauer‐Emmett‐Teller (BET) surface area of 7140 m 2 /g) (Table 1).…”
