本文合成了两种新的黄酮醇衍生物2-(4-(十二烷氧基)苯基)-3-羟基黄酮(DHF)和2-(3,5-双(十二烷氧基)苯基)-3-羟基黄酮(BDHF)，并通过扫描隧道显微镜研究了各自在液/固界面的自组装行为。此外，还添加了一种名为 BisPy 的带有乙炔基的线性吡啶衍生物，以分别调节 DHF 和 BDHF 的组装。然而，只有 BDHF 分子成功地与 BisPy 分子共同组装成网格结构。此外，通过密度泛函理论计算进一步研究了黄酮醇衍生物与BisPy分子的组装和共组装行为机制。该工作将为研究黄酮醇衍生物的自组装以及吡啶衍生物在液固界面调控的共组装奠定基础。
In this paper, two new flavonol derivatives, 2-(4-(dodecyloxy)phenyl)-3-hydroxyflavone (DHF) and 2-(3,5-bis(dodecyloxy)phenyl)-3-hydroxyflavone (BDHF), were synthesized to investigate the respective self-assembly behaviors at the liquid/solid interface by scanning tunneling microscopy. In addition, a linear pyridine derivative with acetylene groups called BisPy was added to regulate the assembly of DHF and BDHF, individually. However, only BDHF molecules successfully co-assembled into grid structures with BisPy molecules. Furthermore, the assembly and co-assembly behavior mechanism of flavonol derivatives and BisPy molecules were further studied by density functional theory calculations. This work will lay a foundation for investigating the self-assembly of flavonol derivatives and the co-assembly regulated by pyridine derivatives at the liquid-solid interface.
