As eries of dye@MOF composites were synthesized through in situ encapsulationo fl uminous rhodamine B( RhB) molecules into ab lue-emissive zirconium-naphthalene-based metal-organic framework (Zr-MOF). The fabricated RhB@Zr-MOFc omposites exhibit tunable dual-emissive characteristics due to the process of resonante nergy transfer from Zr-MOF to RhB. Notably,o ne of the RhB@Zr-MOF composites (R@D3)e xhibited aw eak emissiona t4 20 nm and as tronge mission at 607 nm, for which the two emissions possess large distinctionsi nl ocation and intensity and can be referenced with each other in sensing analytes. By using relative fluorescence intensity insteado ft heir absolute fluorescencei ntensitya st he detection signals, R@D3s erved as ab uilt-in self-calibrated platformt os electively detect Fe 3 + and Cr 2 O 7 2À ions in water.C ompared with the pristine Zr-MOF,t he R@D3 composite showse nhanced sensing selectivity to Fe 3 + and higher sensibility to Cr 2 O 7 2À .T hiss tudy displays the advantageso fc ombining organic dyes with robust Zr-MOFsi nt uning fluorescencea nd sensing performance.

These di-and trichromatic blending strategies may be difficult to implement in the integration process, and can trigger phase separation and color instability during operation. [4][5][6] Another requirement for PC-WLEDs is the stability against thermal quenching, thereby ensuring efficient light emission at working temperatures of up to 200 °C. [7][8][9] Recently, single-phase white-light-emitting materials have been proposed as an alternative strategy to pursue fine color-tunability covering the whole visible spectrum and ensuring high luminescence thermal stability. [10][11][12] The assembly of inorganic and organic photon-emitting components into metalorganic frameworks (MOFs) can result in versatile platforms for generating luminescent functionalities. [13][14][15][16][17][18] In addition to the intrinsic luminescence of the metal and/or the linker, the high degree of porosity in MOFs allows the confinement of luminescent guests. [19][20][21][22][23] The luminescence of such host-guest systems can be tuned by engineering the interactions of the guest with the constituents of the MOFs, offering the opportunity to create single-phase white-light emission. [24][25][26][27][28][29][30][31][32][33] In addition, the Metal-organic frameworks (MOFs) can provide a variety of nanocompartments for the confinement of guest molecules. Furthermore, the emissions of fluorescent molecules can be tuned by confinement. In this study, a solvent-free "bottle-around-ship" method is used to encapsulate perylene and 9,10-dimethylanthracene, two polycyclic aromatic hydrocarbons, in the MOF ZIF-8. Luminescence color tuning is achieved, including white-light emission, when controlling the loading of only a single type of guest. Photophysical analysis suggests that the variations in luminescence result from various guest arrangements in the nanocompartments, as well as host-guest interactions. Because of the tight confinement of the guests, this host-guest system displays excellent luminescence thermal stability.

Metal-organic frameworks (MOFs) enable the design of host-guest systems with specific properties.I nt his work, we showh ow the confinement of anthracene in aw ellchosen MOF host leads to reversible yellow-to-purple photoswitching of the fluorescence emission. This behavior has not been observed before for anthracene,e ither in pure form or adsorbed in other porous hosts.The photoresponse of the hostguest system is caused by the photodimerization of anthracene, which is greatly facilitated by the pore geometry,c onnectivity, and volume as well as the structural flexibility of the MOF host. The photoswitching behavior was used to fabricate photopatternable and erasable surfaces that, in combination with data encryption and decryption, hold promise in product authentication and secure communication applications.
