Recent Progress in Luminous Particle-Encapsulated Host-Guest Metal-Organic Frameworks for Optical Applications

Metal-organic frameworks (MOFs) as a unique class of porous crystalline materials have received comprehensive attention in the past decades. Among them, luminescent MOFs (LMOFs) have been a well-known branch on account of their relevance as optical materials in contemporary era. The establishment of host-guest hybrid LMOF materials has triggered a hot search area owing to the extensive range of applications that can be adjusted by soliciting different functional luminescent guests. Current developments in the thought-provoking application of host-guest LMOFs have stretched into far-ranging fields, including light regulation, imaging, sensing, data encryption, etc. This review discusses on the hybridization of MOFs with functional luminescent particles (LPs) as guests for the construction of a series of extraordinary host-guest luminescent composite materials (LP@MOFs). The basic aspects, involving the preconcentration of MOF hosts and luminous guests as well as the comprehensive synthetic strategies of LP@MOFs are introduced. Furthermore, the applications of luminescent LP@MOF materials are highlighted, with a particular emphasis on the present and continuing challenges and the demand trends of such materials that need to be explored.
