Synthesis, solvatochromism, and photophysical properties of the polymer-tetherable 3-[4-di(2-hydroxyethyl)amino]phenyl-l-(2-furyl)-2-propene-l-one

3-[4-Di(2-hydroxyethyl)amino]phenyl-l-(2-furyl)-2-propene-l-one DAFP has been synthesized as a model compound for the study of molecular interactions in the solid-state and liquid environments with different polarity. The UV/vis absorption spectra of this compound have been studied in 35 solvents of different polarity and hydrogen bonding ability. The solvent dependent UV/vis spectroscopic band shifts ν ˜ max are analyzed using the empirical Kamlet–Taft solvent parameters π* (dipolarity/polarizability), α (hydrogen bond donating capacity), and β (hydrogen bond accepting ability) in terms of the well-established linear solvation energy relationship (LSErs): ν ˜ max = ( ν ˜ max )0 + sπ* + aα + bβ. The solvent independent coefficients s, a, and b and ( ν ˜ max )0 have been determined. To understand the environmental contribution to the fluorescence properties, the fluorescence spectra and fluorescence quantum yields of DAFP were investigated in 12 solvents at 293 K.
