Metal-Organic Frameworks (MOFs) composed of transition metal ions and bridging organic ligands have been extensively studied. The characteristics of MOFs are highly regular channel structures, controllable channel sizes approximating molecular dimensions, designable surface potentials and functionality, and flexible frameworks responsive to guest molecules. Owing to these advantages, successful applications of MOFs range from molecular storage/separation to heterogeneous catalysts. In particular, use of their regulated and tunable nanochannels for a field of polymerization allows multi-level controls of polymerization. This account focuses on recent progress in polymerization using the nanochannels of MOFs, and demonstrates that this methodology for polymer synthesis is a promising strategy for the controlling polymer primary structures, creation of precision polymer assembly, and the design of well-defined nanohybrid materials.
