Physio-chemical and biological Characterizations of 4 Bromo – 4'Chloro Benzylidene Aniline μ-crystals for Engineering Utilities

Abstract

4 Bromo—4’Chloro Benzylidene Aniline - as per suggestion it is named as 4B4CBA; Schiff based organic material has been synthesized and successfully grown by slow solvent evaporation technique. The orthorhombic crystal system of the grown crystal with space group Pccn is confirmed and cell parameters of the grown crystal of 4B4CBA is found by single crystal X-ray diffraction (XRD) analysis. The forming of the C-Cl and C-Br stretching vibrations at 719 cm−1 and 538 cm−1 in Fourier Transform Infra-Red (FTIR) study reveal the confirmation of 4B4CBA compound. The CHNSO analysis shows the presence of element in the 4B4CBA. The lower cutoff wavelength and wide optical absorption window of 4B4CBA exhibit the suitability of the present material for the projective opto-electronic applications. Nonlinear optical efficiency for different micro-crystalline of 4B4CBA is determined by second harmonic generation (SHG) experiment and is also compared with Potassium Dihydrogen Phosphate - KDP material. The electrical studies confirm that the 4B4CBA crystal possess low dielectric constant values at high frequency region. The experiment of photo-conductivity confirms the nature of the photo-conductivity of 4B4CBA crystal. The Scanning electron microscopy (SEM) analysis reveals the morphology of 4B4CBA crystal.
