1,2-bis(4'-n-alkoxybenzoyl)hydrazines (BABH-n, n is the number of carbon atoms in the alkyl chain) are typical liquid crystalline compounds exhibiting bicontinuous cubic (Cub_<bi>) phases. The central core part of the BABH-n molecule is composed of hydrazine group and π-conjugated system. We synthesized new eight compounds. In those compounds, the π-conjugated system is extended from benzene to biphenyl, stilbene, phenylacetylenephenyl, and naphthyl rings while the hydrazine group is preserved. We discuss effects of the chemical structure of the core part on the molecular aggregation state in the Cub_<bi> phases.
