Dynamic Supramolecular Helicity in a Multi-Aluminum Porphyrin Catalyst Enables Stereocontrolled Synthesis of Ultrahigh-Molecular-Weight Isotactic Poly(propylene oxide)

Abstract Isotactic poly(propylene oxide) (iPPO) is a robust polyether with photodegradability. However, its stereoselective synthesis from racemic propylene oxide (rac-PO) remains dominated by preconfigured axially chiral cobalt/chromium bimetallic catalysts. Here, we report an i...

Biodegradable Superabsorbent Polymer from CO2-Based Polycarbonate

Abstract Superabsorbent polymers (SAPs) are widely used but remain dominated by nondegradable poly(acrylic acid)-based networks, creating sustainability concerns. Natural polymer-based alternatives often require acrylic acid grafting to achieve high absorbency, compromising degra...
