Abstract

The invention provides a preparation method of a d-f heteronuclear bimetallic organic framework material based on a monometal coordination polymer. The method comprises the following steps: synthesizing two cases of Ni-based and Dy-based monometal coordination polymers MOFs, namely MOF1 and MOF2, by using a hydrothermal method; and reacting MOF1 and MOF2 used as precursors with dysprosium nitrateand nickel nitrate respectively to successfully prepare the two d-f heteronuclear bimetallic organic frameworks HMOF3 and HMOF4. According to the method, a d-f heteronuclear bimetallic organic framework material HMOFs is prepared by taking monometal MOFs as a precursor. The HMOFs material prepared by the method disclosed by the invention has a coordination unsaturated bimetallic node and relatively large porosity, and is expected to be applied to the fields of gas adsorption and organic catalysis.

Description

technical field

[0001] The invention relates to the field of metal organic frameworks, in particular to a preparation method of d-f heteronuclear bimetallic organic framework materials based on monometallic coordination polymers. Background technique

[0002] Heteronuclear metal-organic frameworks (HMOFs) are assembled by two or more metal ions and organic ligands, which can exert more excellent optical, electrical, magnetic, etc. through the interaction between different metal ions. performance. However, most of the reported work so far has focused on the assembly of single-metal coordination polymers constructed with pure lanthanide ions (Ln) or transition metal ions (Tm), which still face great challenges in the construction of HMOFs. . According to the principle of hard and soft acids and bases (HSAB), lanthanide ions (Ln) and transition metal ions (Tm) have different coordination behaviors. Ln is a hard acid and tends to coordinate with oxygen atoms, while Tm (such as...
