"4f for Future" molecule voted favorite of 2023

Readers of Chemistry & Engineering News (C&EN) elected strontium cyclocene as “standout molecule of 2023“.

In their quest for determining this year’s “most curious, wondrous, and just plain neat molecules“ their choice fell on this new type of supersize sandwich complex created by the groups of F. Weigend, M. Kappes and P. Roesky within the framework of CRC 1573 by coaxing 18 metallocene units to curve into a nanometer-scale ring (a “cyclocene“, cf. Nature paper).
