    First- and second-generation ferrocene-based dendrimers, fullerene and a second-generation liq.-cryst. poly(aryl ester) dendrimer carrying four cyanobiphenyl units were assembled to elaborate polyfunctional materials displaying mesomorphic and electronic properties. The targeted compds. gave rise to enantiotropic smectic A phases and organized into bilayer structures within the smectic layers. Cyclic voltammetry investigations revealed oxidn. and redn. processes in agreement with the presence of both ferrocene and fullerene units. Finally, strong quenching of the fluorescence was obtained for the fullerene-ferrocene dyads suggesting efficient electron transfer from the ferrocene-based dendrimer to fullerene. [on SciFinder(R)]
