Abstract

This work presents a novel passivation method to enhance the photochemical stability of quantum dots (QDs) using polymeric double shell structures from thiol-terminated poly(methyl methacrylate-b-glycidyl methacrylate) (P(MMA-b-GMA)-SH) block copolymer ligands. Cross-linking the GMA epoxides creates a densely cross-linked network, resulting in QDs encapsulated with a robust double layer. The resulting QDs show exceptional tolerance to heat and oxidants, making this approach promising for developing robust light-emitting or light-harvesting devices.
