一约由12个Pd ~（2+）离子和24个双（4-吡啶基乙烯基）取代的弯曲配体组装了一个尺寸为5 nm、近似球形的空心配合物。通过在配体的曲率处放置一个官能团，24个官能团在球形复合物内精确地向内排列。当低聚环氧乙烷被锚定时，中空复合物的空隙被伪聚环氧乙烷纳米颗粒紧密填充，其显示出金属离子（La 3+）吸附性能。
A ca. 5 nm-sized, roughly spherical hollow complex was assembled from 12 Pd2+ions and 24 bis(4-pyridylethenyl)-substituted bent ligands. By putting a functional group at the curvature of the ligand, the 24 functional groups were precisely arrayed inward within the spherical complex. When oligo(ethylene oxide) was anchored, the void of the hollow complex was tightly filled with a pseudo poly(ethylene oxide) nanoparticle, which showed metal ion (La3+) absorption property.
