Abstract
A bichromophoric dyad composed of a Prodan-derived moiety and a BODIPY dye was prepared, photophysically
characterized, and tested for multiphoton fluorescence microscopy of N13 microglial cells. The dyad shows
highly efficient energy transfer, independent on the solvent polarity of the medium. However, in polar media
photoinduced electron transfer is a competitive pathway. The Prodan-derived chromophore shows significant
two-photon absorption. Hence, it can be used a two-photon-absorbing antenna for the sensitization of BODIPY
fluorescence.
