C25

UV/Vis Spectra of C25 in CHCl ₃

FLUORESCENCE OF C25 Absorption maximum: 527.6 nm (CHCl ₃ )
Molar absorptivity: 83 890 (CHCl ₃ )
Fluorescence quantum yield: ~100%
Fluorescence maximum: 534.2 nm (CHCl ₃ )
Singlet lifetime: 3.97 ns
RN 335458-21-4

The Highly Fluorescent Highly Soluble Perylene Dye C25^[1-2]

Calibration of Fluorescence Spectrometers:

The fluorescence quantum yield of C25 is unity over the whole region of UV/Vis absorption, even in the presence of atmospheric oxygen.
No special care for handling of C25 is required because of its high stability.
