International team of chemists successfully synthesizes liquid crystalline aminocyclopropenium salts - important foundation for battery research [ Picture: doi.org/10.1002/anie. Cyclopropenium cations are aromatic three-membered rings and belong to Hückel type aromatic systems. Thus, they are the smaller brothers of the well-known benzene. In contrast to benzene cyclopropenium cations were considered for a long time as curiosities without any practical relevance. However, in recent years their potential as organocatalysts has been recognized. Furthermore, polyelectrolytes carrying aminocyclopropenium subunits have been demonstrated as promising battery materials. However, there was a missing link, i.e. low molecular aminocyclopropenium-based compounds connecting features of organocatalysts and polyelectrolytes.
