Molecular Oligogermanes and Related Compounds: Structure, Optical and Semiconductor Properties.
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)3GeGeMe3(1), Ph3SnGe(SiMe3)3(2), (C6F5)3GeGePh3(3), (p-Tol)3GeSiMe2SiMe3(4), (p-Tol)3GeGeMe2Ge(p-Tol)3(5), (p-Tol)3GeSiMe2SiMe2Ge(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 3.3 eV) was measured for compounds 1-6 showing that those molecules display semiconductor properties.
