以二吡咯二聚体为原料，通过锐角间隔体连接，合成了[2+2]和[3+3]型的多边形金属配合物。电导强烈依赖于化合物的堆积排列，揭示了[3+3]型金属桥组装体中存在有效的空穴跳跃路径，其迁移率高达0.11 cm（2）V（-1）s（-1）沿着排列轴。这些观察结果与环状结构中共轭金属配合物的几何控制相关，这使得它们能够在组装体中有序排列。
Polygon-like [2+2]- and [3+3]-type metal complexes were prepared from dipyrrin dimers connected by acute-angled spacers. The electrical conduction depends strongly on the packing alignment of the compounds, revealing the presence of effective hopping pathways for holes with relatively high mobility up to 0.11cm(2)V(-1)s(-1) along the aligned axis of [3+3]-type metal-bridged assemblies. These observations correlated with the geometrical control of the -conjugated metal complexes in the cyclic structures, which enables their ordered arrangement in the assemblies.
