For his groundbreaking research using metal–organic frameworks (MOFs) to promote the formation of supramolecular structures, Fujita was awarded the 2018 Wolf Prize in Chemistry. MOFs are metal ions that can be linked by organic molecules to form multi-dimensional frameworks. One of the key applications of Fujita’s method, termed metal-directed self-assembly, is to capture proteins in a regular orientation, thereby allowing X-ray crystallography without the need for protein crystallization. Fujita shared the 2018 Wolf Prize in Chemistry with Omar Yaghi of the University of California, Berkeley, who was recognized for his work on MOFs and covalent–organic frameworks (COFs).
