Oxidative control over the morphology of Cu(HHTP), a 2D conductive metal-organic framework.

The morphology of electrically conductive metal-organic frameworks strongly impacts their performance in applications such as energy storage and electrochemical sensing. However, identifying the appropriate conditions needed to achieve a specific nanocrystal size and shape can be a time-consuming, empirical process. Here we show how partial ligand oxidation dictates the morphology of Cu(HHTP) (HHTP = 2,3,6,7,10,11-hexahydroxytriphenylene), a prototypical 2D conductive metal-organic framework.
