A thermal and photostable reference probe for Qr measurements: Chloroform soluble perylene 3,4,9,10-tetracarboxylic acid-bis-N,N'-dodecyl diimide

Abstract

The synthesis of a chloroform soluble perylene 3,4,9,10-tetracarboxylic acid-bis-N,N'-dodecyl diimide via condensation of perylene 3,4,9,10-tetracarboxylic dianhydride and 1,12-diamino dodecane is described. The thermal analysis is shown thermal stabilities above 400 degrees C. Thermal and photostable dye is measured to have a fluorescence quantum yield of unity, Q(f) = 1.00, in chloroform solutions. Perylene bis-dodecyl diimide is an ideal reference probe for fluorescence quantum yield measurements in 500-650 nm region and a reliable soluble photosensitizer for solar photochemical applications.
