Fullerene-ferrocene dendrimer

A mixed [60]fullerene-ferrocene dendrimer (Fig. 65) was also found to be mesomorphic, showing a room temperature smectic A phase which cleared at 157 °C (no glass transition temperature was detected) [294,295]. The mesophase was only slightly destabilized upon the addition of Ceo when com-...

As with chromophores, the steric encapsulation of a dendrimer core can be utilized to prevent intermolecular interactions between redox active sites. A number of different redox active core moieties have been investigated, including, iron—sulfide clusters,9394 bis(terpyridine)iron(II) complexes,92 tris-(bipyridine)ruthenium(II) complexes,330 zinc porphyrins,252 oligothienylenevinylenes,331 fullerenes,236,332 ferrocenes,333-336 oligothiophenes,322 oligonaphtha-lenes,337 and 4,4 -bipyridinium.338... 

Deschenaux and co-workers have designed liquid-crystalline dendrimers containing ferrocene and/or fullerene, all of which are prepared by a convergent and iterative synthetic methodology leading to precisely monodisperse macromolecules.
