Pressure-Modulated Host-Guest Interactions Boost Effective Blue-Light Emission of MIL-140A Nanocrystals.

ABSTRACT: Luminescent metal-organic frameworks (MOFs) have garnered significant attention due to their structural tunability and potential applications in solid-state lighting, bioimaging, sensing, anti-counterfeiting, and other fields. Nevertheless, due to the tendency of 1,4-benzenedicarboxylic acid (BDC) to rotate within the framework, MOFs composed of it exhibit significant non-radiative energy dissipation and thus impair the emissive properties. In this study, efficient luminescence of MIL-140A nanocrystals (NCs) with BDC rotors as ligands is achieved by pressure treatment strategy. Pressure treatment effectively modulates the pore structure of the framework, enhancing the interactions between the N, N-dimethylformamide guest molecules and the BDC ligands. The enhanced host-guest interaction co
