A surprisingly high bending elastic constant ( K 33 ) is obtained in a newly synthesized compound shown here. Mixtures containing a few percent of this compound confirm the influence of the unusual K 33 values, and show an improved electro‐optic response. The origin of the huge K 33 is discussed based on the formation of a smectic cluster structure formed in the nematic phase.
