This paper summarizes the synthesis, growth and the effect of the
position of the substituent in the thienyl ring and also the properties of the
grown chalcone crystals, 2-CTP and 3-CTP. The formation of compound is
confirmed by the re- corded H1NMR spectra. A FT-IR spectrum confirms the presence of all
functional groups in both of the crystals. Single crystal XRD reports that even
though these two compounds crystallize in monoclinic crystal system, 2-CTP has
centro- symmetric P21/c space group and 3-CTP has
non-centrosymmetric space group P21. Thermal properties of grown
crys- tals analyzed by TG/DTA study explain that the 3-CTP compound is
slightly more stable than 2-CTP. The transparency of these isomers in the vis-IR
region has been studied. Second and third order nonlinear optical properties of
3-CTP and 2-CTP crystals have been investigated by powder SHG and Z-scan
technique respectively.read more
