Epitaxial growth of MOF-on-MOF composite is an evolving research topic in the quest for multifunctional materials. In previously reported methods, core-shell MOFs were synthesized via a stepwise strategy that involved growing shell-MOFs on top preformed core-MOFs with matched lattice parameters. However, inconvenient synthesis and strict lattice-matching requirement have limited preparation MOFs. Herein, we demonstrate hybrid mismatching lattices can be under guidance nucleation kinetic...
Abstract The controlled synthesis of multicomponent metal–organic frameworks (MOFs) allows for the precise placement multiple cooperative functional groups within a framework, leading to emergent synergistic effects. Herein, we demonstrate that turn‐on fluorescence sensors can be assembled by combining fluorophore and recognition moiety complex cavity MOF. An anthracene‐based fluorescent linker hemicyanine‐containing CN − ‐responsive were sequentially installed into lattice PCN‐700....
Zirconium-based metal-organic frameworks (Zr-MOFs) exhibit great structural tunability and outstanding chemical stability, rendering them promising candidates for a wide range of practical applications. In this work, we synthesized series isostructural PCN-224 analogues functionalized by ethyl, bromo, chloro, fluoro groups on the porphyrin unit, which allowed us to explicitly study effects electron-donating electron-withdrawing substituents catalytic performance in MOFs. Owing different...
Fluorescent sensing TSRh6G-β-cyclodextrin fluorophore/adamantane-modified inclusion complex magnetic nanoparticles (TFIC MNPs) have been synthesized via the cooperation of a host–guest interaction and sol–gel grafting reaction. Powder X-ray diffraction, transmission electron microscopy, Fourier transform infrared spectroscopy, UV-visible absorption emission spectroscopy employed to characterize material. Fluorescence spectra shown that resultant multifunctional nanoparticle sensors exhibit...
The utilization of reactive oxygen species (ROS) in organic transformations is great interest due to their superior oxidative abilities under mild conditions. Recently, metal-organic frameworks (MOFs) have been developed as photosensitizers transfer molecular ROS for photochemical synthesis. However, visible-light responsive MOFs activation remains scarce. Now we design and synthesize two porous MOFs, namely, PCN-822(M) (M = Zr, Hf), which are constructed by a 4,5,9,10-(K-region) substituted...
With the ever-expanding application scope of metal–organic frameworks (MOFs), framework stability has become a major concern. In article number 1704303, Hong-Cai Zhou and co-workers focus on recent advances in field stable MOFs, covering fundamental mechanisms, design synthesis their latest applications.
Through topology-guided synthesis, a Zr-based mesoporous MOF was successfully constructed, adopting β-cristobalite-type structure. The is embedded with well-arranged terpyridine coordination sites for facile post-synthetic metalation, and can be effectively used as general scaffold the preparation of noble-metal-free catalysts. For instance, scaffolded metal@MOF material exhibits highly efficient catalytic activity alkene epoxidation arene borylation.

Organic molecules with nonlinear optical behavior have advanced a wide range of fields spanning from integrated photonics to biological imaging. With advances in microscopy, an emerging application is multifunctional organic imaging agents. Unlike conventional probes which simply emit light through single or multi photon processes, materials allow systems be simultaneously imaged and controlled. In this work, we report molecular probe for modulating reporting electric fields. The molecule...
