Fullerene-Containing Helical Polymers

Figure 6.1 Schematic illustration of fullerene-containing helical polymers, (a) and (b), and fullerene-encapsulated helical polymers (c).

Poly(cis-phenylacetylene) adopts a helical structure due to steric interaction of the phenyl rings. Chiral [60]fullerene-bisadduct 19 is complexed with anionic polyphenylacetylene 18 to form a fullerene nano-array on the polymer main chain, which induce its macromolecular helicity (Figure 9.22) [95]. Induchon of helicity is sensitive to the geometry of the [60]fullerene-bisadducts. The trans-3 adduct 19 transfers its chiral information onto the macromolecular helicity, whereas trans-2 and cis-3 do not (see Chapter 6 for more details of fullerene-containing helical polymers).
