DOI: 10.1016/j.reactfunctpolym.2019.02.005
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.

DOI: 10.3390/molecules29225392
Abstract: Cyclic polymers have many interesting properties compared to their linear analogs, but there are very few examples of their synthesis. This is because most cyclic polymers have been synthesized by stepwise processes, including synthesizing homo-… read more here.
