: Compared with widely used polyolefin materials, aliphatic polyesters have been primarily used in electronics, packaging and biomedicine owing to its unique biocompatibility and degradability. At present, ring opening polymerization (ROP) of lactone is the main method to synthesize polyesters. Two types of catalysts including metal-based catalysts and organocatalysts were most researched today. However, metal-based catalysts lead to polymer materials with metal residues, which limits its properties and applications. As a result, organocatalysts have received great attention. In this review, the progress of organocatalytic ring-opening polymerization in the past decades were systematically summarized. The potential challenges and development directions in this field are also discussed.

Metal-organic frameworks (MOFs) have been increasingly investigated as templates for precise control of polymerization. Polymerizations within confined nanochannels of porous MOFs have shown unique confinement and alignment effect on polymer chain structures and thus are promising ways to achieve well-defined polymers. Herein, this review will focus on illustrating the recent progress of polymerization within confined nanochannels of MOFs, including radical polymerization, coordination polymerization, ring-opening polymerization, catalytic polymerization, etc. It will demonstrate how the heterogeneous MOF structures (pore size, pore shapes, flexible structures, and versatile functional groups) affect the polymeric products' molecular weight, molecular weight distribution, tacticity, reaction sites, copolymer sequence, etc. Meanwhile, we will highlight some challenges and foreseeable prospects on these novel polymerization methods.
