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 GeGeMe 3 ( 1 ), Ph 3 SnGe(SiMe 3 ) 3 ( 2 ), (C 6 F 5 ) 3 GeGePh 3 ( 3 ), ( p ‐Tol) 3 GeSiMe 2 SiMe 3 ( 4 ), ( p ‐Tol) 3 GeGeMe 2 Ge( p ‐Tol) 3 ( 5 ), ( p ‐Tol) 3 GeSiMe 2 SiMe 2 Ge( 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.
