  • Title: A versatile standard for bathochromic fluorescence based on intramolecular FRET.
    Author: Langhals H, Walter A, Rosenbaum E, Johansson LB.
    Journal: Phys Chem Chem Phys; 2011 Jun 21; 13(23):11055-9. PubMed ID: 21562665.
    Abstract:
    A perylene and a terrylene tetracarboxylic bisimide dyad was prepared in which an efficient energy transfer from the former to the latter is observed. The absorption spectrum of this compound covers a broad range. Bathochromic fluorescence with a high quantum yield was obtained independent of excitation wavelengths (λ < 655 nm). The dyad can be recommended for the use of calibrating fluorescence spectrometers, as well as a fluorescence standard in the bathochromic region.
