A simple protocol for the synthesis of perylene bisimides from perylene tetracarboxylic dianhydride

RSC Advances
PBIs were synthesized from the reaction of perylene bisanhydrides and primary amines in imidazole as solvent. Maleimide, anthraquinone or ferrocene were bonded to the side chain and the S-trityl group was replaced by imidazole in S-trityl cysteine.
