A Cu(ii) metal–organic framework as a recyclable catalyst for ARGET ATRP†
A Cu(II) MOF can serve as an efficient catalyst for activators regenerated by electron transfer atom transfer radical polymerization (ARGET ATRP), e.g. for the synthesis of poly(benzyl methacrylate) (PBzMA) and polystyrene (PS). Furthermore, poly(isoprene) (PI) and poly(4-vinylpyridine) (P4VP) can be formed in a controlled fashion as well, which used to be challenging to achieve by traditional strategies. Taking advantage of the heterogeneous nature of the catalyst, recycling via centrifugation and repeated utilization for at least six cycles are demonstrated.
