在前人研究的基础上，观察到一种含有间苯二甲酸柔性取代基的卟啉衍生物(IPETPP)与较高浓度的冠烯(COR)分子形成的新的共组装。此外，在较低浓度下形成了新的IPETPP自组装，并与CoR分子形成了另一种新的共组装。此外，一系列联吡啶的加入改变了IPETPP的钻石排列，从而提高了双组分结构的稳定性。联吡啶衍生物打破了含有间苯二甲酸取代基的分子间氢键，这是史无前例的。在高度定向的热解石墨上用扫描隧道显微镜研究了所有的共聚体。结合密度泛函理论，揭示了组装结构的形成机理。这些结果将有助于理解界面晶体行为，并可能为调节二元结构提供一条有效的途径。
Based on previous research, a new coassembly formed by a porphyrin derivative (IPETPP), which contains a flexible substituent of m-phthalic acid, is observed with coronene (COR) molecules at a higher concentration. Besides, a fresh IPETPP self-assembly formed at a lower concentration and another new coassembly with COR molecules are obtained. Moreover, the addition of a series of bipyridines alters the diamond arrangement of IPETPP, which enhances the stability of the two-component structures. It is unprecedented that bipyridine derivatives break intermolecular hydrogen bonds containing m-phthalic acid substituents. All the coassemblies are investigated by scanning tunneling microscopy on a highly oriented pyrolytic graphite. Combined with density functional theory, the formation mechanism of the assembled structures is revealed. These results would contribute to understanding the interfacial crystal behaviors and probably provide an efficient pathway to regulate the binary structures.
