Abstract: Benzylideneaniline compounds of N-(4-bromobenzylidene)-4-fluoroaniline (BBFA) and N-(4-bromobenzylidene)-4-methoxyaniline (BBMOA) have been synthesized by the condensation reaction process, and single crystals of these compounds are grown at room temperature by the slow evaporation solution growth technique. The compounds BBFA and BBMOA crystallize in the orthorhombic crystal system with different space groups. Placement of hydrogen atoms in BBFA and BBMOA compounds is confirmed from 1H NMR spectral studies. Fourier transform infrared and Raman spectral analyses are employed to study the presence of functional groups in the compounds. Single stage weight loss and melting point of these compounds are determined from thermogravimetric and differential thermal analyses respectively. Nonlinear optical properties are measured using powder second harmonic generation study and open aperture Z-scan technique. Biological activities are studied using the minimum inhibitory concentration method.
