Due to its high chemical effectiveness the reaction of click chemistry in general and [3+2] cycloaddition (azide alkyne interaction, Huisgen reaction) in particular has found wide application. Thus formed 1,2,3-triazoles represent an important class of heterocyclic compounds with wide applications. Pure organic triazoles with their biological activity are widely used in medicine. At the same time, triazoles containing organometallic groups have been less investigated. Combining an organic fragment and a Group 14 element into one molecule will be promising especially with the view to study structure–property relationships. The correlations established for model compounds can be generalized for oligomers and polymers or semiconducting materials based on Si or Ge. In this report, by combining research into synthetic organometallic and organic chemistry, we plan to begin the application of organic synthesis methods to broaden the diversity of organogermanium compounds [1] for finding the novel properties of these unique derivatives. Based on recent results on σ-delocalized catenated oligomeric [2] and molecular oligoorganogermanes [3] (their wide application in organometallic synthesis, emissive and semiconducting properties) we intend to study the interaction of a simplest example, diethynyl digermane, in the reaction with azides. The target products were investigated by several methods (NMR, UV/vis and luminescence spectroscopy, electrochemistry, XRD analysis), indicating strong impacts of constituent functional groups.
