Conclusions

  1. 1.

    A series of tetracyanopolymethines has been synthesized by condensation of aminals and aminal-acetals of conjugated ω-dimethylaminoaldehydes with malonodinitrile.

  2. 2.

    These tetracyanopolymethines can be used as the anionic components in cation-anion cyanine dyes.

  3. 3.

    The electronic absorption spectra of these newly synthesized dyes were studied in both polar and nonpolar solvents. Specific cation-anion interaction and complex formation has been shown to occur in several of these cation-anion dyes in nonpolar solvents.
