New fluorescentphotochromic compounds (1-H and 1-Boc) have been synthesized and characterized in different solvents. The fluorescence emission can be switched “on” and “off” with visible light and UV, respectively, by means of the photochromic reaction. The emission wavelength and efficiency strongly depend on the polarity of the solvent. The compounds show a positive solvatochromic effect in the
