Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Abstract 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.
