Abstract

Just a pinch of salt: Small amounts of salts accelerate and direct the mechanochemical construction of metal–organic frameworks (MOFs) from a metal oxide (see scheme; ILAG= ion- and liquid-assisted grinding). The resulting rapid and room-temperature synthesis demonstrates the ability to control mechanosynthesis of metal–organic compounds by templating, as well as the ability to use mechanochemistry to include ionic guests within neutral MOFs.
