dc.description.abstractMetal-organic frameworks (MOFs) have become renowned throughout the chemistry and materials communities as an exciting suite of porous material, capable of being designed and adapted to suit various objectives and applications [1]. Aromatic ligands with carboxylate functionalities are a commonly selected organic linker when synthesising MOFs due to their commercial availability and the numerous variable coordination modes exhibited by these functionalities, consequently leading to a high degree of framework connectivity [2]. Structurally similar to 1,4-dicarboxybenzene, frequently used as an organic linker in MOF synthesis, is 1,4-dicarboxycubane due to its para coordination capabilities and carboxylate functionalities. Unlike 1,4-dicarboxybenzene, 1,4-dicarboxycubane is nonplanar in nature, features a higher steric bulk and is void of conjugation within the ring (Figure 1). These differing properties can be exploited to modify the local environment within the pores of resultant MOFs to be more hydrophobic. We have substituted 1,4-dicarboxybenzene with 1,4-dicarboxycubane during the synthesis of known and well-characterised MOFs with the aim of modifying the pore environment within the framework. These MOFs were structurally characterised using single crystal X-ray diffraction and Rietveld refinement of synchrotron X-ray diffraction data collected at the MX and PD beamlines at the Australian . Here we will discuss the structural and behavioural differences between the MOF species, pertaining to their selective gas sorption, water retention and thermal stability properties.en_AU
