MOFs—hybrid materials consisting of metal ions or clusters in coordination bonds with organic linkers—have long been known, and have found their way into a number of niche applications, such as the storage of gases. The recent boom in so-called 2D materials (such as graphene and transition-metal dichalcogenides), however, has accelerated work on synthesizing and characterizing crystalline and porous 2D MOFs, and has raised intriguing prospects for their use in optoelectronics and photonics. In this feature, we take a closer look at 2D MOFs, how they’re synthesized, and their potential optical applications.
