For coordination polymers it is reasonable to assume, and sometimes proven, that in solution, or indeed in a precrystalline state, if we do solidstate synthesis, there are polynuclear entities that without doubt can be called (polymer) macromolecules. These then crystalize or polymerize into the coordination polymer. S. R. BATTEN et al.

Section snippets Synthetic strategies for the preparation of urea and thiourea based CPs and MOFs. Urea or thiourea functionalized frameworks are mainly prepared by the following two strategies: (i) direct synthesis by reaction of urea or thiourea functionalized organic proligands and metal ions; (ii) postsynthetic modification (PSM), whereby urea or thiourea functionalization is incorporated ...

MOFs are constructed from transition metal cations as nodes held in place by multidentate organic ligands containing O or Ndonors as linkers as shown in Fig. 1897, Hoffmann and Kuspert paved the way to MOFs by introducing the first coordination network formed by slow layering diffusion of C 6 H 6 into NH 3 solution of Ni(CN) 2 forming Ni(CN) (NH 3).C 6 H 6.
Metalorganic frameworks (MOFs) are porous coordination polymers consisting of inorganic nodes connected by organic linkers. These materials show chemical variability and topological diversity which predestines them to diverse applications, for example, gas storage and separation, catalysis, sensing, and medicinal applications. However, even after more than 2 decades of research, MOF ...

Initiator driven bulk polymerizations have been studied in significant detail and found utility in the synthesis of a number of commercial polymers [33].As such, it is no surprise that the first study to introduce polymers inside MOFs, carried out by Kitagawa et al. in 2005, was done so using an initiator driven polymerization [32].The group demonstrated that styrene polymerization, carried ...
Metalorganic frameworks (MOFs) or coordination polymers (CPs) have been used as precursors for synthesis of materials. Unlike crystalline MOF, amorphous CP is nonspecific to metal cation species, therefore its composition can be tuned easily. Here, it is shown that amorphous CP can be used as gener .

A reduction in the calculated bandgap has previously been related to an increase in the reactivity of energetic MOFs and coordination polymers (33, 34). Our calculations indicate that a similar relationship might be valid for the reactivity of hypergolic MOFs, as the calculated bandgaps of vinyl or acetylenesubstituted MOFs decrease in the ...
