Cover Story: A sterically hindered spirogermabifluorene was successfully synthesized via the reaction of a dilithiated 3,3’,5,5’-tetra-t-butylbiphenyl ligand with an equimolar amount of GeCl2·(dioxane). Theoretical calculations suggested that the spirogermabifluorene would be generated by the biphenyl-migration from the 5H-dibenzogermole-5-ylidene dimer initially generated in situ, along with the elimination of Ge(0). Its solid-state structure and redox behavior were examined by single-crystal X-ray diffraction analysis and electrochemical measurements, respectively. The sterically hindered biphenyl ligands endow the spirogermabifluorene with high redox stability and increased electron affinity. We believe that several families of spirogermabifluorenes can be accessed using the synthetic methodology described in this paper, which may lead to new applications of spirogermabifluorenes on account of their unique optoelectronic features.View this paper
