Novel asymmetrical single- and double-chiral liquid crystal diads are reported, where diad III-D exhibited the widest range of BPI about 31 °C. Large biaxiality and dipole moment of the bent molecule are useful to extend the BP temperature range.
oxy}benzoyl)oxy]‐phenyl‐4‐[(4‐[(1S)‐1‐methylheptyl]oxy}benzoyl)oxy] benzoate (BC7S), were synthesized to demonstrate control of the helicity of their self‐assembled hierarchical superstructures. Mirror‐imaged CD spectra showed a split‐type Cotton effect after the formation of self‐assembled aggregates of BC7R and BC7S, thereby suggesting the formation of intermolecular exciton couplets with opposite
