Nitroxide-Mediated Controlled Free Radical Polymerization of the Chelate Monomer 4-Styryl-tris(2-pyridyl)borate (StTpyb) and Supramolecular Assembly via Metal Complexation

Abstract: The reaction of 4-(dibromoboryl)styrene with 2pyridylmagnesium chloride resulted in the formation of 4-styryltris(2-pyridyl)borate free acid (StTypb), a new polymerizable nonpyrazolyl "scorpionate" ligand. StTypb did not undergo selfinitiated polymerization under ambient conditions and proved to slowly polymerize through standard radical polymerization at 90 °C. Nitroxide-mediated polymerization (NMP) of StTypb at 135 °C proceeded with good control, resulting in a polymer of M n = 27400 and PDI = 1.21. The TEM… Show more

“…Liu et al have made ruthenium core crosslinked metal‐ion micelles, as well as some magnetic metal‐containing micelles . Jäkle has done nice supramolecular self‐assembly work using metal‐ion coordination of polymer‐supported tris(2‐pyridyl)borates; however, it is not demonstrated to be reversible and the structures are micrometer‐sized . Zhuo et al stabilized micelles using metal‐ion coordination of PEI with both copper and ruthenium and used these to synthesized Pt nanoparticles .…”

“…The NMP method was utilized in the block copolymerization of tris(2-pyridyl)borate ligand-functionalized styrene (see Sect. 3.4) [54]. Alternative approaches include Ziegler-Natta [55,56] and ring-opening metathesis polymerization (ROMP) of borane monomers [57].…”

“…Tpyb ligands are more robust than the Tp ligands, allowing for direct polymerization of the styryl derivative 66 by NMP (Fig. 21b) [54]. The block copolymer 67 was generated by sequential polymerization and its nanostructures and metal complexation were studied.…”
