Abstract
With the introduction of inorganic elements, new polymer materials
with improved and useful properties can be accessed. However, inorganic
polymers are relatively unexplored because the synthetic inorganic chemistry
has presented a challenge. Over the past decade, researchers have targeted
the development of new and controlled routes to polyferrocenylsilanes by
thermal, living anionic and transition metal-catalyzed ring-opening polymerizations.
Polyferrocence block copolymers self-assemble into interesting nanoscopic
architectures such as spherical, cylindrical and flower-like superstructures.
Crystallinity is proved to be a key factor in the formation of nonspherical
superstructures. Preliminary results have shown that these polyferrocenylsilanes
could have broad and useful applications.
