Acridine derivatives have attracted considerable interest in numerous areas owing to their attractive physical and chemical properties. Herein, starting from readily available anthranilic acid, an efficient synthesis of 2,4-bis(arylethynyl)-9-chloro-5,6,7,8-tetrahydroacridine derivatives was accomplished via a one-pot double Sonogashira cross-coupling method. The UV-visible absorption and emission properties of the synthesized molecules have been examined. Additionally, theoretical studies based on density functional theory (DFT/B3LYP/6-31G(d)) were carried out.

2,4-双(芳基乙炔基)-9-氯-5,6,7,8-四氢吖啶：合成和光物理性质


吖啶衍生物由于其有吸引力的物理和化学性质而在许多领域引起了极大的兴趣。本文以易得的邻氨基苯甲酸为原料，通过一锅双Sonogashira交叉偶联法高效合成了2,4-双(芳基乙炔基)-9-氯-5,6,7,8-四氢吖啶衍生物。已检查了合成分子的紫外-可见吸收和发射特性。此外，还进行了基于密度泛函理论（DFT/B3LYP/6-31G(d)）的理论研究。
