Synthesis, spectroscopic and Hirshfeld surface analysis and fluorescence studies of (2E,2'E)-3,3'-(1,4-phenyl-ene)bis-[1-(4-hy-droxy-phen-yl)prop-2-en-1-one] N,N-di-methyl-formamide disolvate.

ABSTRACT: In the bis-chalcone mol-ecule of the title compound, C₂₄H₁₈O₄·2C₃H₇NO, the central benzene and terminal hy-droxy-phenyl rings form a dihedral angle of 14.28 (11)° and the central C=C double bond adopts a trans configuration. In the crystal, the bis-chalcone and solvate mol-ecules are inter-connected via O-H⋯O hydrogen bonds, which were investigated by Hirshfeld surface analysis. Solid-state fluorescence was measured at λ_ex = 4400 Å. The emission wavelength appeared at 5510 Å, which corresponds to yellow light and the solid-state fluorescence quantum yield (F_f) is 0.18.
