研究了由顺式保护Pd（II）配合物和有机三配体组成的两种八面体M6L4笼的自组装过程。是产生比笼大的动力学捕获物种，还是在不形成动力学捕获的情况下组装M6L4笼，取决于寡聚化率和分子内环化率之间的平衡，而这受三同位配体化学结构的微小变化的影响。基于反应网络模型对实验数据进行了数值分析，其中考虑了56种可能的249种反应，揭示了两个M6L4网箱中一个网箱的自组装途径。
The self-assembly processes of two kinds of octahedron-shaped M6L4 cages consisting of cis-protected Pd(II) complexes and organic tritopic ligands were investigated. Whether kinetically trapped species larger than the cages are produced or the M6L4 cage is assembled without the formation of such kinetic traps is determined by a balance between the rates of oligomerization and intramolecular cyclization, which is affected by slight changes in the chemical structure of the tritopic ligand. A numerical analysis of the experimental data based on a reaction network model where 249 reactions between the possible 56 species were considered revealed the self-assembly pathways of one of the two M6L4 cages.
