Abstract

Organosiloxane groups have been used as components of metal-containing liquid crystals (metallomesogens). It has been found that the disiloxane unit aids mesophase formation, stabilising an enantiotropic smectic A phase over a wide temperature range. The overall effect of an organodisiloxane unit is to lower the melting point relative to an alkyl substituted complex while increasing the clearing temperature, or leaving it unchanged, and so ...
