abstract = {The combination of two two-photon-induced processes in a Förster resonance energy transfer (FRET)-operated
photochromic fluorene-dithienylethene dyad lays the foundation for the observation of a quartic dependence of the fluorescence
signal on the excitation light intensity. While this photophysical behavior is predicted for a four-photon absorbing dye, the herein
proposed approach opens the way to use two-photon absorbing dyes, reaching the same performance. Hence, the spatial resolution
limit, being a critical parameter for applications in fluorescence imaging or data storage with common two-photon absorbing dyes, is
dramatically improved.},
