Mesoporous networks embedded within microporous frameworksof zeolites and MOF materials are attracting increasing attentionas they can enhance material properties and boost their performance.Correlating the mesoporous network structure with transport properties,however, remains challenging due to an apparent conflict: most thermodynamicmodels focus on single-pore equilibrium behavior, whereas transportis largely dictated by the organization of the pore network. Herein,we show that exploiting cooperative phenomena in gas adsorption governedby structural disorder resolves this challenge. We present a unifiedframework that links the structure, thermodynamics, and transportby leveraging recent advances in the statistical thermodynamic descriptionof nonequilibrium-phase states arising from cooperativity across porenetworks. Structural descriptors of the mesopore space, extractablefrom gas sorption measurements including, beyond conventional poresize distributions, the average pore connectivity and a hierarchyfactor describing deviations from a fully random structure, are usedto accurately predict diffusive transport.

The behavior is affectedby the components of the material, and the strength of the bonds usedto construct it. For materials that are held together by strong covalentbonds, TE is often reduced as the dimensionality increases. For example,diamond, which is covalently bonded in three dimensions, undergoesless expansion than fullerene, which is a discrete molecule. In molecularsolid materials assembled through noncovalent bonds, TE is generallylarger because the bonds are weaker. Here, we demonstrate synthesisof a series of hydrogen-bonded solids with differing dimensionalityof the hydrogen-bonding network. Notably, the same molecular buildingblocks were used to construct all solids and dimensionality differenceswere achieved by modifying the stoichiometric ratio of the startingmaterials. All solids exhibit anisotropic TE behavior, and systematicallyincreasing the dimensionality affords corresponding control over TE.Moreover, based on unexpected hydrogen-bonding behavior in one solid,a shape-size mimicry approach was successfully used to prepare a ternarymolecular solid. Lastly, one of the two-dimensional (2D) hydrogen-bondednetworks described here exhibits TE behavior that is similar to graphiteand black phosphorus, classic 2D covalent-bond-based materials.
