Amphiphilic block copolymers are versatile structure-directing agents for t
he synthesis of organic nanostructured materials. Chemically well character
ized and easily accessible, they can be utilized for a rich variety of appl
ications. While the prefabrication of an ABC "nanoreactor" or a mesoscopic
casting mold occur via spontaneous self-assembly (exo- and endo-templating)
, during biomimetic mineralization the structure of the resulting inorganic
-ABC hybrid material is induced upon combining the components. The underlyi
ng methodologies are illustrated using recently published, representative e
xamples.
