a
The reactions were performed by treating a solution of the monomer in THF with 1 wt% of sAO at −20 °C for 24 h under an atmosphere of N2.
b
Isolated yield after collection of the precipitate that formed upon pouring the reaction mixture into excess methanol.
c
The number-average molecular weight (Mn) and polydispersity index (Đ) values were determined by GPC and are reported as their polystyrene equivalents. Cbz = carbazole.
