Spectral properties of the perylene dyes. a) absorption spectra of 1, 2, and 3 a in tetrahydrofuran. b) Representative absorption spectra (—) and emission spectra (‐ ‐ ‐ ‐) of the neutral form (black) and anionic form (red) of 2 a in tetrahydrofuran. The insets show photographic images of the dye solutions under daylight (top) and UV (bottom) illumination (λ=365 nm). c) Absorption spectra (—) and emission spectra (‐ ‐ ‐ ‐) of the neutral form (black), monoanionic form (red), and dianionic form (blue) of 3 a in tetrahydrofuran. d) Equilibria of the neutral and anionic forms of 2 a and 3 a.
