Resin-assisted Solvothermal Synthesis Of Metal-organic Frameworks

摘要

Transition metal-exchanged polymer resin beads have been used as a heterogeneous controlled-release source of metal cations in high yielding, phase pure solvothermal syntheses of novel transition metal-organic frameworks.rnThe synthesis of metal-organic frameworks (MOFs) has attracted significant interest due to their structural diversity and vast range of potentially useful applications. Typically MOFs are synthesized using room temperature crystallizations or via hydro(solvo)thermal conditions. Syntheses can take days or weeks and the phase purity of the resulting network solids has always been a major consideration. Synthetic chemists are continuously seeking new synthetic approaches that will deliver cleaner syntheses and greater yields. Recently, microwave-assisted solvothermal synthesis methods have been introduced to dramatically reduce the reaction times for the preparation of known coordination polymers. Traditionally these approaches all involve homogeneous nucleation of MOFs but more recently heterogeneous nucleation on ordered self-assembled monolayers has been used to grow orientated thin films of Cu and Fe-containing MOFs.
