Abstract
Chiral discs: Seemingly flat disc‐like molecules form a columnar phase and spontaneously segregate into macroscopic chiral domains (deracemization). Quantum chemical calculations suggest that these molecules have a twisted axially chiral core (see picture). Their aggregation into chiral superstructures is evidenced by electronic and vibrational circular dichroism spectra.
