In this study, chiral polymers based on amino acids were successfully grafted on the substrates by surface-initiated reversible addition-fragment chain transfer polymerization using oxygen (O2-SI-RAFT) under ambient conditions. Chiral monomers were synthesized using methacrylic anhydride and L/D-amino acids, and chiral polymers were grown on titanium and glass substrates. Block copolymer brushes were also polymerized through chain extension. This is the first report of RAFT polymerization of chiral monomers on the substrate, and the first confirmation of chirality through on-surface CD spectroscopy.
