    In: Macromolecules, 1999, vol. 32, no. 16, p. 5193-5198

    Addition reaction of the malonate-based second-generation ferrocene-containing liquid-crystalline dendrimer 16 to [60]fullerene led to the title compound 1. Molecule 1 showed good solubility in common organic solvents and good thermal stability. Examination of its mesomorphic properties revealed the presence of an enantiotropic smectic A phase, which was identified by...

    Fullerene-containing liquid-crystalline dendrimers

    Dardel, Blaise ; Guillon, Daniel ; Heinrich, Benoît ; Deschenaux, Robert

    In: Journal of Materials Chemistry, 2001, vol. 11, p. 2814 - 2831

    Addition reaction of mesomorphic malonate-based dendrimers (up to the fourth generation) with C60 gave liquid-crystalline fullerene derivatives. The cyanobiphenyl unit was used as liquid-crystalline promoter. The malonates presented nematic and/or smectic A phases. The fullerenes showed only smectic A phases, with the exception of the second generation dendrimer for which smectic A and...
