A synthesis of a new family of chiral dibenzophosphole 5-oxides is described. Using high-yield known reactions we report a method for the synthesis and optical resolution of chiral dibenzophospholes from an unsubstituted system. These molecules are the first examples of a new asymmetrically substituted dibenzophosphole-based group of systems with liquid crystal properties.
Dibenzophospholes: Phase behavior of novel phosphorus-based chiral liquid crystals

, p. 43 - 57 (2007/10/03)
A new family of phosphorus-based chiral liquid crystals is described. Dibenzophosphole oxides containing an asymmetric center at the phosphorus atom show cholesteric and smectic liquid crystalline behavior. The presence of the chiral center in the rigid heterocyclic core avoids the need for destabilizing chiral aliphatic branched substituents at the mesogenic unit. Racemic mixtures of the synthesized dibenzophospholes exhibit both nematic and smectic phases.
