Sustainable hydrogen production from water splitting has emerged as a promising pathway for the storage and conversion of solar energy. Hydrogen is a valuable energy carrier that can be transformed into electricity using fuel cell technology or used in the production of industrially relevant chemicals such as ammonia and methanol. Heterogenization of molecular catalysts combines the advantageous properties of homogeneous and heterogeneous catalysis and facilitates catalyst immobilization onto electrodes of interest. Metal-organic frameworks have received huge attention in the last years as promising porous materials for a wide range of applications, including electrocatalysis. We have demonstrated the successful integration of metal dithiolene units into one and two-dimensional frameworks by using dinucleating and trinucleating thiolate-based ligand scaffolds. The developed metal dithiolene frameworks display remarkable activity for the electrocatalytic conversion of water into hydrogen and electrical conductivity that is switchable from semiconducting to metallic. We expect the design principles discovered in these studies to have a profound impact towards the development of advanced materials and sustainable technologies.
