a high number of functionalized MOF by the PSM. The easy and mild reaction
conditions might be advantage of the CuAAC for the modification of the MOF or the
construction of the MOF conjugates with other functional materials. In addition, the
high yield should be important for the functionalization with mixed ligands and mixed
substrates for the fabrication of multi-variate functionalized MOF. In this section,
we summarized some trials for controlling the functions of the MOF modified by the
CuAAC.
For gas storage, the PSM should be effective tool for controlling the capability of gas sorption. Zhou et al. have reported the control of the functional group
amount of the pore surface by mixing several types of ligands during the MOF
synthesis(Scheme 25.4a) [37]. In this report, they prepared PCN-58 and PCN-59
consisting of zirconium (IV) ions and terphenyldicaboxylic acid ligands. A series of
organic ligands equipped with zero to four azide groups in the benzene ring of the
ligands were prepared and the mixed organic ligands were subjected to solvothermal
synthesis to form various MOF with the various organic ligand ratios. The multivariate MOF has a good reactivity for various alkynes in the pores as well as on the
