single crystal XRD of the crystal shows that the crystal system of 4BP4AP is triclinic with space group P-1. Scanning electron microscope images enunciate the surface smoothness and the two dimensional growth mechanisms in the crystal. The crystal is transparent in the entire visible region as indicated by the UV-VIS-NIR spectrum. The thermal stability and phase transition of the compound was studied
摘要 使用 Claisen-Schmidt 缩合合成了一种新的查尔酮衍生物,3-(4-溴苯基)-1-(pyridin-4-yl)prop-2-en-1-one (4BP4AP),在中心对称结构中结晶。反应法。FTIR 和 FT-拉曼光谱研究在 4BP4AP 上进行结构构象。使用缓慢蒸发溶液生长技术生长单晶。晶体的单晶XRD表明4BP4AP的晶系为三斜晶系,空间群为P-1。扫描电子显微镜图像阐明了晶体的表面光滑度和二维生长机制。该晶体在整个可见光区都是透明的,如 UV-VIS-NIR 光谱所示。通过热重分析和差示扫描量热分析研究了该化合物的热稳定性和相变,发现该化合物在高达 200 °C 时是稳定的。通过开孔径z-scan实验,研究了晶体的非线性吸收和光学限制行为。由于其优异的光物理特性,该晶体可用于光电应用。
