Fourfold negatively charged polyene chains were obtained by reduction of the title compounds 1–3 with alkali metals and investigated with regard to charge storage capacity and minimization of coulomb repulsion. In the novel, expanded π‐systems 1–3 the stilbene subunits are coupled in sterically and electronically different ways.
