Metal-organic frameworks generated from oligomeric ligands with functionalized tethers.

ABSTRACT: Metal-organic frameworks (MOFs) can be prepared from oligomeric organic ligands to prepare materials referred to as oligoMOFs. Studies of oligoMOFs are relatively limited, with most existing reports focused on fundamental structure-property relationships. In this report, functional groups, such as terminal alkynes and pyridine groups, are installed on the tether between 1,4-benzene dicarboxylic acid (H₂bdc) groups of the dimer ligands. It was found that the position of the pyridine donor atom had pronounced effects on the synthesis and structure of Zn(ii)-based isoreticular MOFs (IRMOF-1 analog, oligoIRMOF). Importantly, simple H₂bdc ligands with pendant pyridine groups (i.e., not part of an dimeric ligand), were unable to produce crystalline phases or produced
