We have synthesized two kinds of novel 1,2-bis(4'-alkoxybenzoyl)hydrazine (BABH)-based compounds having siloxane moieties at the end of the alkyl tail. The one has disiloxane moieties in each chain and the other has trisiloxane moieties. Their phase behaviors were investigated by DSC, X-ray diffraction, and polarized light optical microscopy. It was found that both compounds exhibit a cubic phase much wider temperature range than that of the original BABH. However, the structures of the cubic phases were different. The disiloxane compound exhibited a cubic phase with Ia3d symmetry and the other exhibited Im3m symmetry.
