We report time-dependent surface restructuring of bicomponent domain structures of 2,3,7,8,12,13,17,18-octaethyl-21H,23H-porphine (H₂OEP) and cobalt(II) 2,3,7,8,12,13,17,18-octaethyl-21H,23H-porphine (CoOEP) (H₂/Co OEP) driven by self-assembled octanoic acid on the surface of Au(111). Scanning tunneling microscopy (STM) visualized molecular adsorption/desorption and rearrangement of supramolecular architectures in real-time in a solution of octanoic acid. We found that unique domain structures emerged at an initial state guided by adsorbed octanoic acid on the Au surface. Moreover, the desorption of octanoic acid occurred in solution, leading to the surface restructuring of porphyrin molecular networks. This molecular evidence is well-manifested in the time-dependent phase transitions, monitored by in situ STM.

自组装辛酸单层在Au（111）上驱动的卟啉网络的重组

我们报告时间依赖的表面重构的双组分域结构的2,3,7,8,12,13,17,18-八乙基-21H，23H-卟啉（H ₂ OEP）和钴（II）2,3,7 ，8,12,13,17,18-八乙基-21H，23H-吗啡（CoOEP）（H ₂/ Co OEP）由Au（111）表面上的自组装辛酸驱动。扫描隧道显微镜（STM）在辛酸溶液中实时可视化超分子结构的分子吸附/解吸和重排。我们发现独特的结构域结构在金表面吸附辛酸的引导下出现在初始状态。此外，辛酸的解吸发生在溶液中，导致卟啉分子网络的表面重构。通过原位STM监控，这种分子证据在时间相关的相变中得到了很好的体现。
