Synthesis and Flouorescene of 2,3,4,4a,10a,11,12,13‐Octahydro‐1,4a,10a,14‐tetraazaviolanthron‐Derivatives . The tetramethyl derivative 2 of the title compound was prepared by the condensation of neopentanediamine with 3,4:9,10‐perylenebis(dicarboxylic anhydride). The spectra of absorption and fluorescence with λ max = 541 and 563 nm, respectively, show a bathochromic shift versus those of the perylene dyes. The quantum yield of fluorescence is 60 percent. The analogue condensation of the anhydride with ethylenediamine gives a perylene fluorescent dye as an intermediate which contains an amino group and may, therefore, be used in acid aqueous solutions.
