Monomer-Dependent Selectivity in Sulfur-Containing Ring-Opening Copolymerisation: Bimetallic Catalysis for Predictive Design of Degradable Polymers.

ABSTRACT: Sulfur-containing polymers offer unique opportunities for advanced materials due to their inherent degradability, high refractive indices, and potential for chemical recyclability. Yet, synthetic strategies for their precise construction remain underdeveloped and monomer selection rules to achieve this are elusive. Herein, we achieve the first comprehensive evaluation of sulfurated ring-opening copolymerisations (ROCOP) performed under unified conditions using a single heterobimetallic Cr(III)/Rb(I) catalyst platform. Although such catalysts are largely unexplored in sulfur-based ROCOP, our study demonstrates their remarkable synergistic performance in controlling both activity and selectivity across diverse heteroallene/epoxide systems. We identify carbonyl sulfide (COS) as the most promi
