The optical (UV/Vis absorbance, fluorescence in the solid state and in solution) and semiconducting properties of a number of di- and trigermanes as well as related silicon- and tin-containing germanes, 1-6 ((p-Tol)(3)GeGeMe3 (1), Ph3SnGe(SiMe3)(3) (2), (C6F5)(3)GeGePh3 (3), (p-Tol)(3)GeSiMe2SiMe3 (4), (p-Tol)(3)GeGeMe2Ge(p-Tol)(3) (5), (p-Tol)(3)GeSiMe2SiMe2Ge(p-Tol)(3) (6)) were investigated. Molecular structures of 5 and 6 were studied by X-ray diffraction analysis. All compounds displayed luminescence properties. In addition, a band gap (of about 3.3eV) was measured for compounds1-6 showing that those molecules display semiconductor properties.
