Chiral Ligand Controlled Helix-sense-selective Atom Transfer Radical Polymerization of 1-Phenyldibenzosuberyl Methacrylate
The atom transfer radical polymerization (ATRP) of 1-phenyldibenzosuberyl methacrylate was carried out using (-)-sparteine (SP) as ligand. The obtained polymers showed high isotacticity, an excess of right- or left-handed helicity, and were optically active. The control of the stereochemistry might be triggered by the fact that the growing species is complexed with chiral metal complexes and thus the monomer insertion during chain propagation is controlled.
