A Thermal and Photostable Reference Probe for QfMeasurements: Chloroform Soluble Perylene 3,4,9,10-Tetracarboxylic Acid-bis-N, N-Dodecyl Diimide

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 dianhydnde and 1, 12-diamino dodecane is described. The thermal analysis is shown thermal stabilities above 400°C. Thermal and photostable dye is measured to have a fluorescence quantum yield of unity, Qf = 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.
