由光和氧化还原活性结构单元如卟啉和芘组装的金属有机框架（MOF），以及能够在孔内掺入所需化学官能团的许多合成后过程已经标志着这些结晶分子组装体作为用于能量转换和存储系统的新兴类别的组合物。电化学能量转换和存储应用需要在框架内进行有效的电荷传输过程。虽然已知连接体和金属-氧代节点之间的氧化还原电位的大的差异实施跳跃型电荷传输过程，但是金属-氧代节点的影响仅仅是推测性的。部分原因是必须遵循电荷跳跃过程的反离子的参与。这项工作突出了Zr 6
Metal-organic frameworks (MOFs) assembled from the photo and redoxactive building blocks such as porphyrins and pyrenes, as well as numerous post-synthesis processes that enable incorporation of required chemical functionality within the pores have signified these crystalline molecular assemblies as emerging class of compositions for energy conversion, and storage systems. Electrochemical energy conversion and storage applications require efficient charge transport process within the frameworks. While it is known that a large difference in the redox potentials between the linkers and metal-oxo nodes enforces a hopping type charge transport processes, the impact of the metal-oxo nodes is merely speculative. Part of the reason being the involvement of counter ion that must follow the charge hopping process. This work highlights impacts of Zr6
