Description
Moritz Schmidt and colleagues reported a chemistry study in 2026 on a rigid molecule built around two silicon atoms. Related frameworks with two boron atoms act as acid-like partners, while versions with two phosphorus atoms act as base-like partners. Getting both behaviors from a single kind of atom had required mixing two different elements. The team built a silicon-only frame and tested whether careful chemical reduction could switch its behavior on demand.
The starting molecule acted in an acid-like way toward a magnesium partner, forming a doubled butterfly-shaped product. Removing electrons in controlled steps gave two reduced forms. One behaved as a base-like partner toward the boron framework, and the other showed both behaviors in a single reaction, giving a three-ring product. Crystal analysis confirmed structures. The authors present controlled reduction as a flexible way to design cooperative main-group chemistry.
