Abstract

Abstract: The rediscovery of graphene in 2004 has started an enormous chase in the research of 2D materials. A new family of layered 2D materials consisting of the 14th group elements beyond carbon has already been reported. Here, a new methodology in germanene chemistry is presented using germanane (Ge6 H6 ) as a stable and easily accessible starting material for effective synthesis of novel germanene derivatives. The modification procedure utilizing strong bases—alkali metal arenides—for deprotonation of germanane and its subsequent functionalization with p ‐nitrobenzyl bromide is described. Functionalization of germanene is confirmed by FT‐IR, Raman, and XPS spectroscopy as well as by X‐ray diffraction analysis. Abstract : 2D‐Materialien : Eine neue Methode in der Germanenchemie wird vorgestellt, die Germanen (Ge6 H6 ) als stabiles und leicht zugängliches Ausgangsmaterial für die effektive Synthese neuartiger Germanenderivate verwendet.
