Aksakal, Suzan published the artcileTransformation of Thioester-Initiated Star Polymers into Linear Arms via Native Chemical Ligation, Application In Synthesis of 7575-23-7, the main research area is thioester initiated linear arm star polymer native chem ligation; copper-mediated polymerization; native chemical ligation; star polymers; thioester initiators.
The synthesis of a new class of Cu-mediated polymerization initiators with thioester functionality is demonstrated and their polymerization kinetics via single-electron transfer living radical polymerization is reported. From periodic sampling, it is found that thioester- or ester-based initiators can be employed interchangeably, resulting in very similar polymerization rates. Furthermore, a multifunctional thioester initiator is employed for the preparation of a well-defined four-arm star-shaped polymer. It is further shown that the full dissociation of the star polymer into linear arms via native chem. ligation can easily be followed via size exclusion chromatog., as a result of the change in hydrodynamic volume Finally, the obtained linear polymers are characterized via matrix-assisted laser desorption/ionization-time of flight mass spectrometry and found to be in good agreement with the expected mol. weight distribution that confirms the successful transformation.
