3-(2,4-Dichlorophenyl)-1-(4-methylphenyl)prop-2-en-1-one

Abstract

The title compound, C16H12Cl2O, exhibits second-order nonlinear optical properties as it crystallizes in a non-centrosymmetric space group. The dihedral angle between the benzene rings is 34.02 (6)°. Intermolecular C—H...O interactions link the molecules to form chains along the c axis.

“…1). Bond lengths and angles in (I) are in normal ranges (Allen et al, 1987) and comparable with those in related structures (Patil, Teh et al, 2006;Shettigar et al, 2006;Patil, Ng et al, 2007;Patil, Chantrapromma et al, 2007). The dihedral angle between the two benzene rings is 45.94 (8)° in molecule A and 46.82 (7)°i n molecule B.…”

“…Among several organic compounds reported for their NLO properties, chalcone derivatives are prominent materials due to their excellent blue-light transmittance and ease of forming crystals. They provide the configuration necessary to show NLO activity, with two planar rings connected through a conjugated double bond (Patil, Teh et al, 2006;Patil, Ng et al, 2007;Patil, Rosli et al, 2007). The title compound, (I), was prepared as part of our ongoing studies on non-linear optical materials Shettigar et al, 2006;Chantrapromma, Jindawong et al, 2006;Chantrapromma, Ruanwas et al, 2006).…”
