Front Cover: Experimental and Theoretical Structure Elucidation of the [2 : 1] Complex Ion of Carbo[n]helicene with n=6, 7 and 8 and Ag⁺ (ChemPhysChem 21/2023)

The Front Cover illustrates the competition of [6]-, [7]- and [8]helicene for attaining a silver(I) cation during solvent evaporation in electrospray ionization. In this competition, the larger helicenes outperform the smaller ones. This first step is eventually leading to the formation of a [2:1] complex in which one helicene is attached via π–π stacking to a [1:1] tweezer complex. Cover design by Christoph Oleszak.
