H-shaped,n-shaped and X-shaped rod-coil molecules,consisting of biphenyls and a p-terphenyl or phenyl unit linked together with ether bonds as a rod segment and poly(propylene oxide) (PPO) with a degree of polymerization (DP) of 12 or poly(ethylene oxide) (PEO) with a DP of 17 as coil segments were synthesized.These molecules contain lateral alkyl groups in the middle of benzene ring and lateral methyl groups between the rod and coil segment.The self-assembling behavior of these molecules was investigated by means of DSC,POM and SAXS in the bulk state.
