Abstract: Abstract Charged cyclic polymers, e.g. cyclic DNAs and polypeptides, play enabling roles in organisms, but their synthesis was challenging due to the well-known “polyelectrolyte effect”. To tackle the challenge, we developed a templated method to… read more here.

DOI: 10.1021/acs.macromol.8b01681
Abstract: The synthesis of defect-free cyclic poly(3-hexylthiophene) (P3HT) was achieved for the first time by the GRIM polymerization using an appropriate initiator, cyclization by a Pd-mediated end-to-end coupling reaction, and two isolation processes using functionalized resins… read more here.

Abstract: The N-heterocyclic carbene 1,3-di-tert-butylimidazol-2-ylidene (NHCtBu) and its 1:1 adduct with methyl sorbate (MS) were found to initiate anionic polymerization of N-substituted maleimides (RMIs) in organic solvents at −20 °C to afford linear and cyclic poly(RMI)s, respectively.… read more here.

DOI: 10.1039/d3ra01614e
Abstract: 1,3-Di-tert-butylimidazol-2-ylidene (NHCtBu), a typical N-heterocyclic carbene (NHC), was previously found to induce the anionic chain-growth polymerization of ethyl sorbate (ES) in the presence of an aluminum Lewis acid, i.e., methylaluminum bis(2,6-di-tert-butyl-4-methylphenoxide) (MAD), in which the… read more here.
