Synthesis, single crystal structure and spectroscopic aspects of chalcone 2(2E)-1-(4′-bromobiphenyl-4-yl)-3-(2, 3-dimethoxybenzaldhyde) prop-2-ene-1-one

Abstract The title compound, (2E)-1-(4′-bromobiphenyl-4-yl)-3-(3,4-dichlorophenyl)-3-hydroxypropan-1-one (BDCP) was synthesized, spectrally characterized (IR, UV, FT-IR, 1 H NMR, and FT-Raman), and its three- dimensional structure was confirmed by single crystal diffraction studies. In addition, Second Harmonic Generation (SHG) efficiency of the crystal, thermogravimetric analysis (TGA), and powder XRD were performed. The bromo phenyl ring makes a dihedral angle of 50.8 (2) 0 and 34.5 (2)° with the methoxy phenyl ring and central phenyl moiety. The dihedral angle between the methoxy phenyl ring and the central phenyl moiety is 17.1(2) 0 . The short contacts C9—O1…Cg1 and C3—H3…Cg3 are involved in crystal structure stabilization. The SHG conversion of the BDCP is found to be 1.33 times that of Urea.
