Influence of structural isomers of naphthalene diimides on photophysical and electrochemical properties

Abstract Three structural isomers of naphthalene diimides were synthesized. In all compounds, the electron-withdrawing diimide group exhibits a stable two-step reduction behavior under electrochemical conditions, and it was revealed that their reduction potentials vary significantly depending on the position of the diimide group relative to the naphthalene ring.
