Synthesis and mesomorphic properties of some anthraquinone derivatives: New difunctionalised discotic monomers

Some new 9,10-anthraquinone (rufigallol) derivatives have been prepared and their mesomorphic properties have been studied. The unsymmetrically substi tuted tetrahydropyranyloxy-ethers (THP-ethers), exhibited columnar mesomorp hism at fairly low temperatures and the xray studies carried out for one of the homologues confirmed the hexagonal nature of the mesophase. The deprot ected derivatives of these THP-ethers, also form columnar mesophases. All t hese derivatives are very good candidates for polymerisation studies.
