Highly fluorescent 1-phenylnaphth[1,2,3-<I>cd</I>]indol-6(2<I>H</I>)-one (<B>3b</B>) and its 7-chloro and 7-amino derivatives were synthesized by reaction of 1-aminoanthraquinones with benzyl chloride in KOH–DMSO system, followed by treatment with aluminium chloride. The compound <B>3b</B> was easily <I>N</I>-alkylated with various alkyl halides in KOH–DMSO system. The fluorescence quantum yields (<I>Q<SUB>f</SUB></I>) of naphth[1,2,3-<I>cd</I>]indol-6(2<I>H</I>)-one derivatives 3 were high (0.5–0.7), except for 7-amino derivatives which did not fluoresce. The <I>Q<SUB>f</SUB></I> of 7-chloro derivative (<B>3d</B>) was strongly dependent on solvent: 0.37 in ethanol; 0.02 in acetonitrile; 0 in benzene. The compounds <B>3</B> were demonstrated to be efficient laser dyes for 500–550 nm region.
