Perylene pigments as alternatives to phthalocyanine and indanthrone blue

Abstract A series of new chromophores were synthesized which comprise carboximide and ureido auxochromic moieties attached to a perylene core. The blue perylene pigment possesses a strong intramolecular push-pull effect as well as intermolecular hydrogen bonding. With its optical characteristics and excellent photostability, the pigment holds promise as an alternative to phthalocyanine blue and indanthrone blue in traditional pigment applications such as coatings, plastics, and even high-tech fields such as color filters and organic electronics.
