A “peelable banana” is formed when a bent‐core molecule is linked to a rodlike mesogen through a flexible aliphatic spacer. This is an appropriate description of this novel low‐molar‐mass organic system, which displays a transition from a biaxial nematic (N b ) phase to a biaxial smectic A phase. The illustration gives a schematic representation of the dimeric molecules in the N b phase as well as the corresponding textural and conoscopic patterns obtained.
