Résumé
New boron containing two-photon absorbing fluorophores have been prepared. Centered on a pyrazabole central core, various conjugated systems and end groups were investigated to modulate their physicochemical properties (alkoxy, diphenylamino, and boron dipyromethene groups). One and two-photon photophysical characterizations were performed, showing efficient fluorescence in organic solvents. High two-photon absorption cross sections were determined in the 500-800 nm range. Two-photon excited microscopy images were also obtained with these new boron containing fluorescent bioprobes with laser intensities in the milliwatt range.
