    Summary
    Structure-properties relations of liquid crystalline fullerene-containing poly(aryl ester)/poly(benzyl ether) dendritic compounds with variation of C60 linkage type have been analyzed based on experimental data on their total polarity and electro–optical Kerr effect in benzene solutions. There was established that fulleropyrrolidine as the core of dendrimer strongly restricts rotational freedom of dendrons, in contrast to methanofullerene. A conclusion that not only terminal mesogenic groups and dendrons' generation number, but a manner of C60 incorporation into the dendritic matrix also influences on the mesomorphic behavior of these multicomponent hybrid-type liquid crystalline compounds had been made.
