Harvesting substituents enables π-stacked dimers of antiaromatic cation

Caption

“Harvesting” peripheral substituents reveals a highly planar antiaromatic molecule (homoHPHAC cation). Despite electrostatic repulsion between positively charged species, the molecules adopt a slip-stacked arrangement, forming a stable π-stacked dimer. This stacking induces electronic reorganization, leading to partial attenuation of antiaromaticity. The terraced landscape in the background symbolizes the potential for creating new modes of molecular assembly through rational molecular design.
