“…From the membrane preparation perspective, the method used currently (dissolution of the polymer followed by solvent evaporation) could be further improved if the pioneering works by Kitagawa and co-workers on polymerization inside MOF nanochannels are considered [114][115][116][117][118][119][120][121][122]. Once the basis of the process has been gathered, it is easy to envisage that MOF nanoparticles can be linked to each other to form continuous MOF layers, for instance, by direct polymerization of monomers at the external surface of the MOF nanoparticles.…”

“…The Kitagawa group has developed strategies to perform polymerization confined within the voids of MOFs. [68][69][70][71][72] Macromolecules confined in nano spaces should have distinctly different properties when compared to those in the bulk state due to the formation of specific molecular assemblies and conformations. As shown in Figure 5, the single polystyrene (PSt) chains are confined within highly regular one-dimensional nanochannels of a porous coordination polymer [Zn 2 (bdc) 2 ted] n (bdc: 1,4-benzenedicarboxylate, ted: triethylenediamine).…”

The incorporation of metallic units into polymer chains has emerged as a promising route towards functional metal-containing (nano)materials. The resulting polymers possess rich functions derived from their metallic elements, such as redox, optical, catalytic and magnetic properties. In addition, the directional and dynamic nature of metal coordination interactions provides further variables for the exploration of novel materials with designed nanostructures. These types of polymers can be synthesized through direct metal-ligand coordination or chain polymerization of metal containing monomers. Depending on the polymerization techniques and starting components, the resulting polymers, akin to their organic counterparts, can be produced in the form of insoluble networks, processible chain structures, gels or colloids. Research into this rising multidisciplinary subject has benefited from recent progress in several related areas such as supramolecular chemistry, colloidal chemistry etc., with the combination of the relative merits of each ensuring further developments in each individual discipline. For example, as a result of studies into organometallic block copolymers self-assembly behavior, living supramolecular polymerization has been unprecedentedly realized for the architectural design of micelles (see image on the right). Nevertheless, the field is still in a developmental stage and offers ample opportunities for fundamental research, as well as material exploration. In this Feature Article, we intend to overview the field with a brief survey of recent literature.

“…26 As a consequence of the hostguest redox reaction, the Fe III ions are reduced to the Fe II ions, accompanied by polymerization of the monomers to polypyrrole (PPy) and the release of the pillar counter anions for charge compensation (Figure 10). Although PCPs with redox-active metal ions might be capable of providing controlled reactions for oxidized/reduced products in the resulting composites, only a few reports on the use of PCPs for redox reactions have been reported because of the low framework stability of PCPs during the redox reaction.…”

“…27 An interesting template effect of 3 on morphology and assembly of polymer objects was observed in this work. 26 Removal of the host framework of 3 in EDTA solution allowed 2011)isolation of the intercalated PPy as an insoluble black precipitate. When we conducted SEM measurements, the morphology of the isolated PPy was found to be platy in contrast to the granular morphology of the bulk PPy prepared by oxidation of Py with K 3 [Fe III (CN) 6 ] in water (Figure 11).…”

In nature, biopolymers are efficiently synthesized by multilevel arrangements of monomers within constrained molecular-level spaces. These biological systems produce regio-and stereoregular polymers with uniform molecular weights, and can also arrange the higher order structures of the resulting polymers. Inspired by the elegant operations of polymerization in biological systems, polymer synthesis in artificial confined geometries is a promising strategy for the control of polymer primary structures and the design of well-defined nanostructures. Recently, we have established a new methodology for controlling polymer synthesis using microporous coordination compounds. In this account, recent progress and future perspectives of polymerizations in these coordination nanospaces are reviewed.
