Luminescent metal–organic frameworks exhibit great potential as materials for nanophotonic applications because of their programmable properties and tunable structures. In particular, luminescent guests (LG) can be hosted by due to porosity guest confinement capacity, forming LG@MOF composite systems. However, such guest–host systems are mainly produced loose powders, preventing widespread use in practical devices technological that require implementation a stable continuum solid. this regard, using monolithic MOF hosts might workable option solve challenge. Herein, we reported the facile synthesis fabrication novel prototypical sol–gel systems, designated LG@monoMOF. Red (rhodamine B), blue (7-methoxycoumarin), yellow (fluorescein) emitting dyes were encapsulated robust UiO-66 host, resulting red, blue, light-emitting monoliths. The mechanical photophysical characterization three LG@monoMOF was systematically carried out order unravel role interactions optical response bespoke composites.
