Demonstration of a Two‐Electron Pathway in Piezoelectric Mechanochemistry: Synthesis and Mechanical Adaptation of Polythiourethane

open access: yesAngewandte Chemie, EarlyView.
A mechano‐triggered polythiourethane (PTU) synthesis mediated by a two‐electron pathway. The polymerization proceeds efficiently (<1 h) under focused ultrasound, achieving >90% conversion without any conventional base catalyst. The approach demonstrates broad compatibility with various thiol/isocyanate monomer combinations, highlighting its synthetic ...
