Engineering the racemization barrier in Z-shaped perylenediimides: axial chirality governs the self-assembly of core-twisted scaffolds.
In this work, we describe the demanding synthesis of two core-twisted Z-shaped perylenediimide derivatives, 1 and 2, together with the separation of their individual M and P enantiomers. Z-PDI 1 exhibits axial chirality as its only source of asymmetry, whereas Z-PDI 2 incorporates also peripheral stereogenic centers. T...
