Carbon dioxide (CO2) is considered a renewable one-carbon building block for chemical synthesis owing to its abundance, low toxicity, nonflammability, and availability. The incorporation of CO2 into the polymer backbone affords various ester- or carbonyl-containing moieties, which create desired material properties impart unique degradability after use under microbial conditions. In this Perspective, we focus on critical advances in CO2-derived polymers highlight catalytic strategies, novel conceptual routes, potential application fields. outlook perspective are provided describe future challenges new strategies establishing CO2-based with performances economic competitiveness comparable that petroleum-based materials.

The scientific community has witnessed extensive developments and applications of organoboron compounds as synthetic elements metal-free catalysts for the construction small molecules, macromolecules, functional materials over last two decades. This review highlights achievements organoboron-mediated polymerizations in past several decades alongside mechanisms underlying these transformations from standpoint polymerization mode. Emphasis is placed on free radical polymerization, Lewis pair ionic (cationic anionic) polyhomologation. Herein, alkylborane/O

Poly(cyclopentene carbonate) (PCPC) produced by copolymerization of CO2 and cyclopentene oxide (CPO) is a promising but challenging chemical recyclable polymer that has high potential in minimizing plastic pollution maximizing utilization. Currently, problems remain to be solved, include low reactivity toxic metal catalysts, inevitable byproducts, especially the ambiguous mechanism understanding. Herein, we present first metal-free access PCPC using series modular dinuclear organoboron catalysts. was afforded an unprecedented catalytic efficiency 1.0 kg PCPC/g catalyst; while depolymerization abides combination pathway random chain scission unzipping, returning CPO near-quantitative yield (>99 %). The preparation along with depth understanding related mechanisms would helpful for further development advanced catalysts plastics.

We herein report the synthesis of commercially attractive low molar mass polycarbonate polyols obtained through ring-opening copolymerization CO2 and epoxides, using a series borinane-based bifunctional organocatalysts in presence chain transfer agents (CTAs). These catalysts enable CO2/epoxide copolymerizations with high linear vs cyclic selectivity outstanding productivity for both poly(cyclohexane carbonate) (18.2 kg/g catalyst) poly(ether propylene (1.1 catalyst). exhibit all features living processes; resulting polycarbonates could be precisely controlled by varying [monomer]/CTA ratio. The performance these implying loading shows great potential applications large-scale preparation CO2-based polyols.
