“…To design MOFs with desired properties, the introduction of various functional groups into MOFs has attracted considerable interests. Postsynthetic covalent modication provides a variety of means to chemically modify the structures of MOFs, [18][19][20][21] among which the direct graing of functional groups on the organic linkers is effective, and has been widely applied.…”

A postsynthetic covalent strategy involving dual-acyl chloride has been developed to introduce uncoordinated carboxyl groups into amine containing metal-organic frameworks (MOFs). The carboxyl group functionalized MOFs have been characterized by various techniques, including X-ray diffraction patterning, scanning electron microscopy, Fourier transform infrared spectroscopy, nuclear magnetic resonance, thermal gravimetric analysis, and gas adsorption. Results clearly indicated uncoordinated carboxyl groups were successfully grafted to the MIL-101(Cr)-NH 2 framework. In addition, most of the amine groups (>80%) were grafted with carboxyl groups, which indicates this method is very effective.The thermal stability and adsorption selectivity of CO 2 /N 2 were substantially enhanced, albeit the BET surface areas and total pore volumes were reduced. These observations could be explained by the effect of elimination of macropores in the framework due to the projecting of new functional groups in pore apertures. Here the successful fabrication of a MOF with uncoordinated carboxyl groups provides the possibility of efficiently modifying other MOFs.

“…A qualitative proof for the incorporation of multiple linkers is usually unproblematic and can be confirmed by IR spectroscopy, XPS, XAS, solid‐state NMR spectroscopy and in some cases by single‐crystal analysis ( D ) . Moreover, UV/Vis spectroscopy can be used to prove the incorporation of certain linkers and might be able to quantify the linker ratios for certain systems …”

In recent years, the synthesis of mixed‐metal and mixed‐linker metal–organic frameworks with multiple metals and/or linker molecules combined in one framework has become a growing field of interest. These mixed‐component or multivariate metal–organic framework materials provide the possibility to introduce multiple functionalities inside one framework. The interaction of guest molecules with different functionalities in the same material is a promising approach in the fields of gas storage, separation, catalysis and drug delivery. Furthermore, the combination of different components may lead to synergistic effects that cannot be achieved otherwise. These mixed‐component approaches open up new pathways to an even larger range of possible customizations in the field of metal–organic frameworks.

Bioinspiration has emerged as an important design principle in the rapidly growing field of materials science and especially its subarea, soft matter science. For example, biological cells form hierarchically organized tissues that not only are optimized and designed for durability, but also have to adapt to their external environment, undergo self‐repair, and perform many highly complex functions. Being able to create artificial soft materials that mimic those highly complex functions will enable future materials applications. Herein, soft matter technologies that are used to realize bioinspired material structures are described, and potential pathways to integrate these into a comprehensive soft matter research environment are addressed. Solutions become available because soft matter technologies are benefitting from the synergies between organic synthesis, polymer chemistry, and materials science.
