The nitro group in the isomeric condensation products of 4-nitronaphthalic-1,8-anhydride with 1,2-diaminobenzene namely 3-nitro and 4-nitro-7H-benzimidazo[2,1-a]benz[de]isoquinolin-7-one is displaced by reaction with 1-octylamine, to give in the case of the 4-nitro compound the highly fluorescent 4-octylamino derivative. The condensation product from 4,5-dinitronaphthalic-1,8-anhydride and 1,2-diaminobenzene afforded, by nitro group displacement with either 1-butylamine or 1-octylamine, complex mixtures without exhibiting significant fluorescence.
