Abstract
Polymers have become one of the major types of materials that are essential in our daily life. The controlled synthesis of value-added polymers with unique mechanical and chemical properties have attracted broad research interest. Metal–organic framework (MOF) is a class of porous material with immense structural diversity which offers unique advantages for catalyzing polymerization and oligomerization reactions including the uniformity of the catalytic active site, and the templating effect of the nano-sized channels. We summarized in this review the important recent progress in the field of MOF-catalyzed and MOF-templated polymerizations, to reveal the chemical principle and structural aspects of these systems and hope to inspire the future design of novel polymerization systems with improved activity and specificity.
Highlights
This review summarizes the recent advances in Metal–organic framework (MOF)-catalyzed polymerization, and grouped literature in two main sections, including the unique MOF-based catalysts for polymerization without templating effect (Figure 1A), and MOF-controlled polymerization through templating effect (Figure 1B)
Schmidt group [91] proposed a new method for polymer synthesis through the combination of the porous MOF structures with reversible deactivation radical polymerization techniques, such as the connection of activator regenerated by electron transfer atom transfer radical polymerization to MOF
We summarized the application of MOF for oligomerization and polymerization reactions into two categories
Summary
Metal–organic frameworks (MOFs), constructed from inorganic nodes and organic linkers, have emerged as a new class of hybrid materials ordered into two- or three-dimensional network [1,2]. MOFs feature uniform pores that preferentially interact with substrates with the proper shapes and sizes [25] Both the inorganic node and organic linker allows for the introduction of various functional group [26]. One remaining challenge is to build a catalyst system that can controlled the polymerization process across the length of multiple monomers to achieve unique morphology, regioselectivity, and even sequence specificity [43,44,45] This level of control would allow the synthesis of polymers with greatly enhanced structural complexity, to better fit our need in developing advanced biomedical materials. This review summarizes the recent advances in MOF-catalyzed polymerization, and grouped literature in two main sections, including the unique MOF-based catalysts for polymerization without templating effect (Figure 1A), and MOF-controlled polymerization through templating effect (Figure 1B)
