The first example of an exceptionally stable naphthalenediimide‐based dianion in ambient and hot water is reported, forming one of the most stable redox‐active dianions. Taking a cue from the electronic conduits prevalent in biomolecules, we employed for the first time disposition of donor imide oxygen and acceptor cyano orbitals to form a pair of noncovalent intramolecular electronic‐bridge, which assists in dianionic charge delocalization. The multi‐stage redox property, NIR absorption, and amenability to water can be attractive for green energy applications. For more details, see the Full Paper by P.
