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...
