One of the Schiff base 4-bromo-4'dimethylamino benzylideneaniline (BDMABA) compounds was synthesized and single crystal of the material was grown by solvent evaporation method at room temperature. Molecular structure of BDMABA was confirmed by (1)H nuclear magnetic resonance and the presence of functional groups was confirmed by Fourier Transform Infrared and Fourier Transform Raman spectral analyses. Cell parameters were determined using single crystal X-ray diffraction analysis and crystalline perfection of the grown BDMABA crystal was evaluated using high-resolution X-ray diffraction analysis. Thermal analyses indicated that the material is thermally stable up to 215 °C and its melting point is 161.5 °C. Vickers microhardness study was carried out to estimate the mechanical hardness of BDMABA crystal which shows that the crystal belongs to the class of soft materials. Linear and nonlinear optical studies were carried out using UV-vis-NIR spectrum and open aperture Z-scan technique respectively.
合成了席夫碱 4-溴-4'-二甲基氨基苯亚甲基苯胺（BDMABA）化合物之一，并采用溶剂蒸发法在室温下生长出该材料的单晶。通过（1）H 核磁共振确认了 BDMABA 的分子结构，并通过傅里叶变换红外和傅里叶变换拉曼光谱分析确认了官能团的存在。使用单晶 X 射线衍射分析确定了晶胞参数，并通过高分辨率 X 射线衍射分析评估了生长的 BDMABA 晶体的结晶度。热分析表明，该材料在 215°C 以下热稳定，熔点为 161.5°C。进行维氏显微硬度研究以估计 BDMABA 晶体的机械硬度，结果表明该晶体属于软材料类别。使用紫外可见近红外光谱和开孔径 Z 扫描技术分别进行了线性和非线性光学研究。
