(2E,4E)-1-(3-Nitrophenyl)-5-phenylpenta-2,4-dien-1-one

Abstract

In the title compound, C17H13NO3, the dihedral angle between the benzene rings is 2.57 (4)°. The crystal structure is stabilized by C—H...O interactions, which form a three‐dimensional network, and by C—H...π interactions.

Growth and characterization of a new organic nonlinear optical crystal: 1-(3-Nitrophenyl)-5-phenylpenta-2,4-dien-1-one

“…The SHG signal provides a highly sensitive and definitive test for the absence of a center of symmetry in the compound. The Ci3NC crystal can be considered as a donor-π-acceptor-π-acceptor system, where charge transfer takes place from donor to acceptor group.The presence of donor-acceptor groups, charge transfer axis, parallel head to tail arrangement in crystal packing, and the number of intermolecular bonding enabled Ci3NC to have higher SHG efficiency than urea [11].…”

“…The general synthetic strategy employed to prepare 1-(3-Nitrophenyl)-5-phenylpenta-2,4-dien-1-one was based on Claisen-Schmidt condensation, which has been previously reported [11]. The chemical structure of Ci3NC and the schematic representation of the reaction is given in Scheme 1.…”

“…We have already reported synthesis and single crystal structure of Ci3NC [11]. Ci3NC (C 17 H 13 NO 3 , Mr¼279.28) crystallizes in the orthorhombic space group P2 1 2 1 2 1 with lattice parameters a ¼7.0167 (1) Å, b ¼12.1953 (2) Å, c ¼16.1081 (3) Å and there are four molecules per unit cell [11]. As a part of extensive characterization, we present in this article, the investigation of the crystal growth, transmission cutoff, the SHG efficiency, nonlinear absorption and refraction, thermal expansion and HRXRD of this material.…”
