Abstract

Two compact far-red cationic benzoquinone diimine dyes were synthesized, having molecular weights lower than 400 or 300 Da and featuring light absorption properties centered around 700 nm. Their redox and optical properties were investigated experimentally, alongside theoretical studies of their structural and excited-state characteristics.
