The molecular factors underpinning the twist–bend nematic phase in liquid‐crystalline dimers and bimesogens are now largely understood. The discovery of a linear relationship between T NTB–N and T N–Iso taken in conjunction with experimental demonstration of the importance of bend angle demonstrates that this mesophase is driven by gross shape, the minimisation of free or excluded volume and entropy.
