%X We describe the helical stereomutation in the kinetically controlled coassembly of the reported carbonyl‐bridged triarylamines (CBTs). The copolymerization of chiral CBTs (S)‐1 or (R)‐1 with achiral 2 in sergeants‐and‐soldiers (SaS) experiments results in a tuneable helicity conditioned by the percentage of the chiral sergeant and by the cooling rate. The dissimilar inherent chirality of the extended monomeric (M) and intramolecularly H‐bonded metastable (M*) species as well as the different stability of the kinetic trap of the chiral CBTs (S)‐1/(R)‐1 and the achiral CBT 2 condition the chirality transfer and afford J‐aggregates of inverse handedness
