A porphyrin derivative called 5,15-di(4-carboxyphenyl)porphyrin (H₂DCPp) with carboxyl groups successfully self-assembled on a highly oriented pyrolytic graphite (HOPG) surface and its co-assembly structures with three kinds of pyridine molecules were investigated by scanning tunneling microscopy (STM) with atomic resolution. H₂DCPp arranged in a long-range ordered structure, and both 1,4-bis (pyridin-4-ylethynyl) benzene (BisPy), 4,4′-bipyridine (BP) and 1,3,5-tris(pyridin-4-ylethynyl) benzene (TPYB) molecules successfully regulated the host molecules as guest molecules. The well-organized model optimized by density functional theory (DFT) calculations reveals the detailed behavior of the assembly characteristics and regulation of porphyrin derivatives, which is helpful for the research and development of solar cells and nanodevices.

不同吡啶对含有两种对称苯甲酸的卟啉衍生物的调控

一种名为 5,15-二(4-羧基苯基)卟啉 (H ₂ DCPp) 的具有羧基的卟啉衍生物成功地自组装在高度取向的热解石墨 (HOPG) 表面上，其与三种吡啶分子的共组装结构是通过具有原子分辨率的扫描隧道显微镜（STM）进行研究。H ₂DCPp 以长程有序结构排列，1,4-双（吡啶-4-基乙炔基）苯 (BisPy)、4,4'-联吡啶 (BP) 和 1,3,5-tris(pyridin-4 -ylethynyl) 苯 (TPYB) 分子成功地将主体分子调节为客体分子。通过密度泛函理论（DFT）计算优化的组织良好的模型揭示了卟啉衍生物的组装特性和调控的详细行为，有助于太阳能电池和纳米器件的研究和开发。
