Abstract The 4-(1,3-dioxoisoindolin-2-yl)antipyrine, C19H15N3O3, was synthesized by the condensation reaction of 4-aminoantipyrine and phthalic anhydride in ethanol solution using triethylamine as catalyst, and characterized by X-ray diffraction and spectral techniques. The experimental spectral bands were structurally assigned with the theoretical calculation, and the thermodynamic properties of the
摘要 以三乙胺为催化剂,4-氨基安替比林与邻苯二甲酸酐在乙醇溶液中缩合反应合成了4-(1,3-二氧异吲哚啉-2-基)安替比林,C19H15N3O3,并通过X射线衍射和光谱技术表征。 . 通过理论计算对实验光谱带进行了结构分配,并从理论计算的频率中获得了所研究化合物的热力学性质。在 B3LYP/6-31G(d) 水平计算的线性极化率 (α0) 和第一超极化率 (β0) 分别为 33.6921 A3 和 2.7835 × 10-30 cm5/esu。NBO 分析表明,所研究的分子具有长程电子转移的结构特征,能隙为 ⩾ 3.639 eV。前沿分子轨道负责电子极化和长程电子转移特性。结果表明,该化合物可能是光响应材料的极好候选者。
