Exploration of Chemically Cross-Linked Metal–Organic Frameworks
摘要:
A series of geometrically constrained, cross-linked benzene dicarboxylic acid (bdc) derivatives have been synthesized and incorporated into the canonical isoreticular metal-organic framework (IRMOF) lattice. Only certain cross-links, which allow for the proper relative orientation of the bdc subunits, form the desired IRMOF. Design criteria from these cross-linked ligands allowed for the rational design of two oligomeric ligands composed of three bdc monomers tethered together. These oligomeric ligands were also readily incorporated into an IRMOF lattice with a high degree of crystallinity and porosity, providing a new dimension to rational ligand design for metal-organic frameworks.

conventional molecular linkers or polymeric linkers (polyMOFs), but the relationship and relative properties of these related materials remain understudied. As an intermediate between these two extremes, a library of oligomeric ligand precursors (dimers, trimers) was used to prepare a series of oligomeric-linker MOFs (oligoMOFs) based on the prototypical IRMOF-1 system. IRMOF-1 was found to be remarkably
