Laterally extended naphthalene tetracarboxylic bisimides.
The colorless naphthalene tetracarboxylic bisimides were laterally extended with imidazole rings to give colored and highly fluorescent materials. Donor-substituted phenyl groups at the imidazole rings cause further bathochromic shifts in fluorescence where the strong solvent influence in the spectra is typical for a TICT process. Applications are discussed.
