• We show that diradicaloid helical conjugated molecules can display strong through‐space bonding interactions. These interactions are analogous to π‐stacking pancake bonding widely observed for dimers and other aggregates of stable π‐conjugated radicals. We show that these multicenter interactions can have a significant stabilizing effect, but they depend in subtle ways on the specific overlap and relative orientations of the radical carrying subunits. The specific through‐space interactions between the radicaloid units occur at specific size ranges of the helical molecules. All in a twist: Helical diradicaloid molecules can display strong through‐space π‐stacking pancake bonding. These multicenter two‐electron bonding interactions between the radicaloid terminal units occur at specific size ranges of the helical molecules.
