Structure and spectral properties of Fluorol-7GA), 2-butyl-6-(butylamino)-1H-benzo[de]isoquinoline-1,3(2H)-dione, see the structure shown as an insert ). Spectra of molar absorbtivity in 0.1 M Na-Hepes buffer (pH 7.4) containing 0.6 mg/ml HPCD and in methanol are shown by solid and dashed lines, respectively. Spectrum of emission (excitation at 405 nm by a diode laser) is shown in dashed-and-dotted line.
