Mild activation of water-soluble naphthalene diimides (NDIs) as bisalkylating agents has been achieved by base catalysis and by chemical and electrochemical reductions. NDI activation by a single electron reduction represents a novelty in the field of activatable electrophiles. Under mild reduction, induced by S2O42- in aqueous solution, the resulting NDI radical anion (NDI•-) undergoes a monomolecular

Solid-state thermoelastic behavior—a sudden exertion of an expansive or contractive physical force following a temperature change and phase transition in a solid-state compound—is rare in organiccrystals, few are reversible systems, and most of these are limited to a dozen or so cycles before the crystal degrades or they reverse slowly over the course of many minutes or even hours. Comparable to thermosalience
