  Anchoring of Diphenylphosphinyl Groups to NH ₂ ‐MIL‐53 by Post‐Synthetic Modification

  摘要：

  AbstractIncorporation of new functionalities into metal–organic frameworks (MOFs) by post‐synthetic modification is a most attractive strategy for attaining the desired properties without risking destruction of the crystalline structure chosen for the aimed application. In this work the amine group in NH2‐MIL‐53(Al) was used as anchoring point for the diphenylphosphinyl (Ph2PO–) moiety. The success of the derivatization was confirmed by 31P MAS NMR and DRIFT spectroscopic studies. A newly synthesized reference linker bearing the same phosphinic amide functional group was used to assist in the MOF characterization. The introduction of the bulky diphenylphosphinyl group stabilizes the large‐pore form of the MOF and leads to changes in the optical properties as a consequence of the electronic influence of the PO group. The approach described here is relevant for the preparation of novel phosphorus‐containing MOFs.
