Iodine is an attractive candidate for living radical polymerization owing to its strong halogen bonding ability and the vigorous C―I bond
enabling diverse mechanisms including iodine transfer polymerization (ITP)
reverse iodine transfer polymerization (RITP)
reversible complexation mediated polymerization (RCMP)
and atom transfer radical polymerization (ATRP). Am
ong them
iodine-mediated ATRP stands out for its high activation rate constants
low equilibrium constants
and convenient post-polymerization modification. However
the use of alkyl iodides as initiators remains challenging because they are thermally and photochemically unstable. To solve this question
RITP mechanism was incorporated into the ATRP for the
in situ
generation of the alkyl iodide from I
2
. Further studies revealed that the ATRP ligands could also trigger the RCMP mechanism. Kinetic studies
radical trap experiments
and density functional theory (DFT) calculations clarified the contributions of each mechanism. This RITP/RCMP/ATRP ternary polymerization avoids the use of unstable initiators and achieves controlled polymerization of various monomers.
