By reaction of di‐n‐alkyl 4‐hydroxybenzylidene‐malonates with different acid chlorides three homologous series of swallow‐tailed compounds were synthesized. The products were characterized by microscopic and calorimetric investigations and show nematic and smectic behaviour. As X ray studies prove the relatively broad molecules are statistically antiparallel arranged within the smectic monolayers.
