A novel type of mesogenic molecule and a new way of introducing chirality into liquid‐crystalline compounds are both realized in roof shaped 1 , obtained as a mixture of three diastereoisomers. Compound 1 forms an S C *mesophase between 102 and 119°C, and its electro‐optic switching behavior in an electric field fits the law characteristic of ferroelectric liquid crystals.
