Description
Summary:In the bischalcone molecule of the title compound, C24H18O4·2C3H7NO, the central benzene and terminal hydroxyphenyl rings form a dihedral angle of 14.28 (11)° and the central C=C double bond adopts a trans configuration. In the crystal, the bischalcone and solvate molecules are interconnected via O—H...O hydrogen bonds, which were investigated by Hirshfeld surface analysis. Solid-state fluorescence was measured at λex = 4400 Å. The emission wavelength appeared at 5510 Å, which corresponds to yellow light and the solid-state fluorescence quantum yield (Ff) is 0.18.
