Abstract

Salicylidene-aniline (SA) derivatives have been synthesized and characterized for optical and nonlinear optical properties. The substituents used as methyl (-CH₃), chloro (-Cl), and nitro (-NO₂) groups. These substituent groups show a variation in their electro-negativity characteristics and hence have the capacity to perturb the electrons system in the parent ring structure of the salicylidene-aniline compound. Material characterization has been done using various analytical tools namely: DSC, FTIR, UV-VIS and GC/MS. The nonlinear optical characterization has been done using the Kurtz powder efficiency method. The nonlinear refractive index and the third order susceptibility have been determined using the Z-Scan method in solution using ethanol as the solvent. The Kurtz powder efficiency measurements using urea as standard gives the values as 0.7 for 3-Cl SA, 0.8 3-NO₂ SA and 1.0 for the 3-CH₃ SA derivative. The results of single bulk crystals grown using the Bridgman-Stockbarger method are reported.
