Abstract

Benzimidazole and naphthoimidazole derivatives of N-alkylperylenedicarboximide were prepared by the condensation of N-alkyl-3,4:9,10-perylenetetracarboxylic acid monoanhydride monoimide with o-phenylenediamine and diaminonaphthalenes. Properties of these derivatives as pigments were tested, and the thermal stability and solubility of these derivatives were also investigated.
