Abstract

A novel chalcone derivative (E) 1-(furan-2-yl)-3-(4-bromophenyl) prop-2-en-1-one (2AF4B) has been synthesized and crystallized using slow evaporation solution method. The grown single crystals were characterized by Fourier transform infrared vibrational technique to confirm the functional groups. The thermal stability of the crystals has been examined by TG/DTA/DSC measurements. The 2AF4B crystals are thermally stable up to 224°C. The grown single crystals are characterized for their mechanical hardness. The 2AF4B crystals possess high optical transmittance beyond cut-off wavelength in the entire visible region. The energy band gap of the material is found using Tauc's plot and by a direct method. The mechanical hardness, thermal stability, and optical transparency of the novel organic materials reveal the uprightness in nonlinear optical device fabrication.
