Polarized optical micrographs of the macroinitiators M-poly-L-1 (a) and P-poly-L-1 (b) and the respective block copolymers initiated by the two macroinitiators (c–f). (g) Schematic representation of the enantiomer-selective and helix-sense-selective living block copolymerizations initiated by the macroinitiators with left- and right-handed helical structures.
