morphology of compounds shows a cuboid structure with identical particles. Compounds (I) and (II) are pure, according to thermal analysis, and no decomposition takes place before the melting point. In addition, two-dimensional fingerprint plots and Hirshfeld surface analysis were employed to calculate the intermolecular contacts in the compounds.
苯乙酮和取代的醛在 NaOH 催化剂存在下简单缩合生成查耳酮。使用单晶的 X 射线衍射分析来解决和增强结构。密度泛函理论 (DFT) 用于评估 B3LYP/6–311G++ (d, p) 基组水平的优化分子结构。Kubelka-Munk 函数和 Tauc 图用于确定化合物 (I) 和 (II) 的能带隙。化合物的表面形貌显示出具有相同颗粒的长方体结构。根据热分析,化合物(I)和(II)是纯的,在熔点之前没有发生分解。此外,还采用二维指纹图和 Hirshfeld 表面分析来计算化合物中的分子间接触。
