The solid‐state emmissive chalcone (2E)‐1‐(5‐chlorothiophen‐2‐yl)‐3‐[4‐(dimethylamino)phenyl]prop‐2‐en‐1‐one

Orange rectangular blocks suitable for X‐ray diffraction analysis were obtained for the previously reported [Ahmad & Bano (2011). Int. J. ChemTech Res.3, 1470–1478] title chalcone, C15H14ClNOS. This solid‐emissive chalcone exhibits a planar structure and the bond parameters are compared with related compounds already described in the literature. The determination of the structure of this chalcone is quite relevant because it will play an important role in theoretical calculations to investigate potential two‐photon absorption processes and could also be useful for studying the interaction of such compounds with a biological target.
