Discovery of a crucial clue to accelerate the development of carbon-neutral porous materials

Metal-organic frameworks (MOFs) have been gaining attention as promising carbon-neutral porous materials, thanks to their high performance in gas storage, separation, and conversion. The geometric building blocks of MOFs, metal clusters and organic linkers, allow chemists to predict and synthesize new structures like assembling LEGO. However, finding new metal building blocks is still a daunting challenge due to the complex nature of metal ions in synthesis.
