The title compound, NO2-F2PA, exhibited solvatochromic emission, that is, the emission spectra of hexane and toluene were different from each other and the emission was quenched in THF, acetone, ethanol, and acetonitrile. In addition, the amorphous film of NO2-F2PA exhibited vapochromic emission. Reddish orange emission of the film at ambient atmosphere changed to yellowish green one upon exposure to hexane vapor and recovered to the original after drying. On the other hand, the emission of the film was quenched upon exposure to THF and ethanol vapors.
