Recent Progress in 2D Metal‐Organic Frameworks for Optical Applications

Abstract

Abstract 2D metal‐organic frameworks (MOFs) have attracted broad research interest in recent years owing to their unique dimension‐related properties for widespread applications in catalysis, energy storage, conductivity, and optoelectronic devices. In this review, first the strategies for the rational design and precise construction of 2D MOFs are introduced. Then, the synthesis of 2D MOFs and their nanosheets by using top‐down and bottom‐up methods are summarized. Subsequently, the recent advances in optical/photonic applications of these 2D MOFs are highlighted, with special focus on lighting and display devices, nonlinear optics, as well as the luminescent sensing and biomedicine applications. Finally, the future potentials and challenges for the construction of 2D MOFs for optical materials are outlooked.
