表面配位聚合物的形成是由化学反应性和结构单元的相互作用以及基底注册的定向作用控制的。除了结构组装的预定模式之外，所涉及的反应物的化学反应性可能为其聚集提供替代途径。在表面反应中转化的有机分子随后可能通过同质或异质金属吸附原子的配位而被捕获，这也可能在分子转化中发挥作用。氨基官能化苝衍生物，4,9-二氨基苝醌-3,10-二亚胺 (DPDI)，根据存在的吸附原子（Fe、Co、Ni 或 Cu）的性质，经历特定水平的脱氢（-1 H-2 或 -3 H-2）。通过这种方式，分子被转化为内配体或外配体，具有凹或凸排列的配位原子，这对于 ID 或 2D 配位聚合物的形成至关重要。
The formation of on-surface coordination polymers is controlled by the interplay of chemical reactivity and structure of the building blocks, as well as by the orientating role of the substrate registry. Beyond the predetermined patterns of structural assembly, the chemical reactivity of the reactants involved may provide alternative pathways in their aggregation. Organic molecules, which are transformed in a surface reaction, may be subsequently trapped via coordination of homo- or heterometal adatoms, which may also play a role in the molecular transformation. The amino-functionalized perylene derivative, 4,9-diaminoperylene quinone-3,10-diimine (DPDI), undergoes specific levels of dehydrogenation (-1 H-2 or -3 H-2) depending on the nature of the present adatoms (Fe, Co, Ni or Cu). In this way, the molecule is converted to an endo- or an exoligand, possessing a concave or convex arrangement of ligating atoms, which is decisive for the formation of either ID or 2D coordination polymers.
