Understanding how the constitutional dynamics of a dynamic combinatorial library (DCL) adapts to surfaces (compared to bulk solution) is of fundamental importance to the design of adaptive materials. Submolecular resolved scanning tunneling microscopy (STM) can provide detailed insights into olefin metathesis at the interface. Analysis of the distribution of products has revealed the important role of environmental pressure, reaction temperature, and substituent effects in surface‐confined olefin metathesis. We also report an unprecedented preferred deposition and assembly of linear polymers, and some specific oligomers, on the surface that are hard to obtain otherwise.

烯烃复分解驱动的表面受限动态共价系统

了解动态组合库（DCL）的构造动力学如何适应表面（与本体解决方案相比）对于自适应材料的设计至关重要。亚分​​子分辨扫描隧道显微镜（STM）可以提供有关界面处烯烃复分解的详细见解。对产物分布的分析揭示了环境压力，反应温度和取代基效应在表面受限烯烃复分解中的重要作用。我们还报告了在表面上难以获得的线性聚合物和某些特定的低聚物的前所未有的优选沉积和组装。
