Nanostrukturierung von Festkörpern mit amphiphilen Polymeren

Amphiphilic block copolymers are versatile structure-directing agents for the synthesis of organic nanostructured materials. Chemically well characterized and easily accessible, they can be utilized for a rich variety of applications. 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 thc components. The underlying methodologies are illustrated using recently published, representative examples.     

Strukturaufklärung von N6-, 9- und 7-Acyladeninen durch 1H-und 13C-NMR-Spektroskopie von Festkörpern und in Lösung

Structure Determination of N⁶-, 9-and 7-Acyladenines by ¹H- and ¹³C-NMR Spectroscopy of Solids and in Solution . Adenine (1) reacts with carboxylic acid anhydrides or chlorides 2 to yield the acyladenine isomers 3–5 . The isomeric structures were determined by ³³C- and ¹H-NMR spectroscopy in solution and by solid-state ¹³C-NMR spectroscopy.
