Abstract
Two-dimensional (2D) metal-organic frameworks (MOFs) have attracted considerable attention owing to their fascinating properties, including ordered crystalline structures, large surface areas, and related unique 2D properties. Moreover, 2D MOFs have been widely used in energy, catalysis, and optoelectronic applications. However, researchers have performed fewer investigations on photonic applications. To remedy this gap in knowledge, recent progress in the development of 2D MOFs for photonic applications was investigated. First, the background and motivation of this review are introduced. Then, the synthesis method and properties are presented, followed by an introduction to their photonic device applications. Finally, future research prospects and challenges in 2D MOFs for photonic applications are proposed. (C) 2022 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement
