Solution
With the objective of establishing the effect of cycloalkanone ring size on the NLO properties of bischalcones para-substituted diarylideneacetone and substituted diarylidenecycloalkanone derivatives were synthesized by the Claisen–Schmidt condensation reaction and characterized by using UV-vis, FT-IR, 1H NMR, 13C NMR and mass spectrometry. The second harmonic generation (SHG) efficiencies and third-order nonlinear optical (NLO) properties of the synthesized compounds were studied. Among all the synthesized compounds, 2,6-bis-(4-methoxybenzylidene) acetone showed the highest SHG efficiency (12.96 times that of urea) and 2, 6-bis–(4-methylthiobenzylidene) cyclopentanone showed the highest third order NLO property with χ (3) value of 2.650 ± 0.02310-13. Among the diarylidenecycloalkanones SHG efficiency decreased with an increase in the cycloalkanone ring size. Diarylidenecyclopentanone series showed the best third-order NLO activity followed by diarylideneacetone, diarylidenecycloheptanone, and diarylidenecyclohexanone series. The results indicate that the cycloalkanone ring size as well as the presence of substituent on the aryl ring affect the NLO properties.
