A key to address advanced MOF materials suitable for more sophisticated applications is to add functionalities of greater complexity in a controlled manner. We report a generic and original post-synthetic modification method starting from amino derived MOFs. The first step consists in converting the amino group into azide (N3). Without isolation nor purification, the desired functionalized material is obtained by grafting the corresponding alkyne using “Click Chemistry”. This work reports for the first time the synthesis of a two-dimensional combinatorial library of 24 functionalized MOFs. We also show that the grafting yield can be controlled from 10 to 100%. Finally, we compare the effect of the grafting yield on the porous volume of (1D) and (3D)MOF porous structures. [ABSTRACT FROM AUTHOR]

The article presents a study which aims to develop a one-pot, two-step functionalization method from the existing amino-derived metal-organic framework (MOF) compounds. The study converted an amino-MOF to its corresponding azide compound and then "clicked" a synthon onto an azide in order to obtain the desired functionalized material. It says that a possible direct functionalization from amino-derived MOFs can occur and that the method enables complete functionalization even for large groups.
