Synthesis and properties of a new photostable soluble perylene dye: N,N '-Di-(1-dehydroabietyl) perylene-3,4,9,10-bis(dicarboximide)

N,N'- Di-(-1-Dehydroabietyl) perylene-3,4,9,10-bis(dicarboximide) is prepared in 95 % yield by the condensation of perylene 3,4,9,10-tetracarboxylic dianhydride with dehydroabietyl amine. Thermal and photostable bright red-orange dye is measured to have a fluorescence quantum yield of unity, Q(f) = 1, in chloroform solutions. Solubility of the dye is 1.8 g/L in chloroform. The diimide is an ideal reference probe for fluorescence quantum yield measurements in 500-650 nm region and also very interesting dye for chemiluminescent light devices.
