Crystal Structure, Vibrational, Optical, and Photoluminescence Analyses of Schiff Base 4-Bromo-N′-[(5-bromo-2-hydroxyphenyl)methylidene]benzohydrazide Single Crystals
Single crystals of 4-bromo- N ′-[(5-bromo-2-hydroxyphenyl)methylidene]benzohydrazide (4BMB) were grown using the slow evaporation method. The examination of the crystal structure through the utilization of single-crystal x-ray diffraction analysis revealed that the 4BMB crystal underwent crystalliza...

′-[(5-bromo-2-hydroxyphenyl)methylidene]benzohydrazide (4BMB) were grown using the slow evaporation method. The examination of the crystal structure through the utilization of single-crystal x-ray diffraction analysis revealed that the 4BMB crystal underwent crystallization within the monoclinic crystal system, featuring a centrosymmetric space group denoted as Pn. Verification of the presence of anticipated functional groups was achieved through analysis of Fourier transform infrared and Raman spectra. The crystal demonstrated a wide optical bandgap of 5.87 eV with a cutoff wavelength of 222 nm. At 532 nm, the crystal exhibited transmittance of 63%, and refractive index and extinction coefficient values of 2.097 and 4.1827 × 10
−6
, respectively. Photoluminescence spectra revealed a prominent peak at 491 nm associated with blue-green emission. In addition, it exhibited strong emission at 430 nm. Additionally, confirmation of the blue emission of the crystal was obtained through the CIE color chromaticity coordinates diagram. The calculated correlated color temperature value of the crystal was 1753 K. The crystal exhibits essential properties that make it suitable for applications in organic light-emitting diodes.
