The two-dimensional thin metal-organic frameworks (MOF) sheet has emerged as a promising hybrid material for applications in catalysis and optoelectronic devices. However, the small size large thickness of an MOF still pose barriers toward its potential applications. Herein, micron-sized ultrathin is synthesized with assistance benzoic acid. Benzoic acid promoted coordination porphyrin center copper ions, reduced H-stacking J-aggregation between layers, induced anisotropic growth sheet....
A novel porphyrin-based two-dimensional metal–organic framework (MOF) nanodisk with small size and few layers was prepared by coordination chelation between <italic>meso</italic>-tetra(4-carboxyphenyl)porphine ligand Zn(<sc>ii</sc>) paddlewheel metal nodes.
Here, ferric oxide-loaded metal–organic framework (FeTCPP/Fe2O3 MOF) nanorice was designed and constructed by the liquid diffusion method. The introduction of iron metal nodes loading Fe2O3 can effectively catalyze Fenton reaction to produce hydroxyl radicals (•OH) overcome hypoxic environment tumor tissue generating oxygen. monodispersity porosity porphyrin photosensitizers in MOF structure exposed more active sites, which promoted energy exchange between molecules oxygen for photodynamic...
A three-dimensional hemin-functionalized graphene hydrogel (Hem/GH) was prepared by a facile self-assembly approach. The as-prepared Hem/GH showed good mechanical strength with storage modulus of 609-642 kPa and high adsorption capacity to organic dye contaminants (341 mg g-1 for rhodamine B). Moreover, could be used as photosensitizer the photocatalytic degradation dyes displayed superior photodegradation activity methylene blue (MB). This result better than that counterparts such (GH)...
A novel gadolinium–porphyrin metal–organic framework (MOF) nanosheet was synthesized by coordination chelation between gadolinium(III) ions and 4,4,4,4-(porphine-5,10,15,20-tetrayl) tetrakis (benzoic acid) (TCPP). The mechanism molecular structure of the prepared Gd-TCPP products were analyzed through comparison (benzenesulfonic (TPPS) TCPP. MOF nanosheets exhibit a high relaxation rate 40.8 mM–1 s–1, which is better than rates for most reported contrast agents. In addition, photosensitive...
The intramolecular ligand-to-metal charge transfer (LMCT) process acts as a fluorescence switch in MOF nanomaterials, effectively quenching or enabling fluorescence.
Brain-computer interface (BCI) allows the human or animal brain to directly interact with external environment through neural interfaces, thus playing role of monitoring, protecting, improving/restoring, enhancing, and replacing body.
Novel Au-decorated Te hybrids with a tripod-shaped planar microstructure were prepared through two-step hydrothermal process: the synthesis of single crystals and subsequent self-sacrificial reaction template HAuCl4. Based on influences temperature solvent compositions as-obtained microstructures, plausible mechanism was proposed to account for formation Au/Te crystals. The as-prepared have sensitivity 6.35 μA/ppb in electrochemical detection As(III), which represents highest reported...
We report a general method for the fabrication of three-dimensional (3D) macroporous graphene/conducting polymer modified electrode and nitrogen-doped graphene electrode. This involves three consecutive steps. First, 3D (3D MG) was fabricated electrochemically by reducing oxide dispersion on different conducting substrates used hydrogen bubbles as dynamic template. The morphology pore size MG could be governed use surfactants dynamics bubble generation departure. Second, graphene/polypyrrole...
In this work, porphyrin-based MOF nanosheets were formulated. The as-developed Gd-TCPP could be protonated significantly in an acidic solution, which greatly enhanced the UV-vis absorption at 665 nm. Also, a significant structural reorganization occurred to achieve nanowire structure. As center of porphyrin had metal coordination atom, Q band better stability due their inability protonated. These results confirm that MOFs can regulated via protonation, and protonation solution avoided by...
The design and synthesis of a novel generation nanoscaled platform with imaging-guided therapy remain real challenge. It can not only improve the imaging sensitivity tumor tissues for guiding all kinds treatments but also reduce harm healthy tissues. Here, polydopamine (PDA), polyethylene glycol (PEG), c(RGDyK) peptide (RGD)-modified cisplatin-loaded Gd2Hf2O7 nanoparticles (Gd2Hf2O7@PDA@PEG-Pt-RGD NPs) are designed magnetic resonance (MRI)-guided combined chemo-/photothermal-/radiotherapy...
Photodynamic/photothermal therapy (PDT/PTT) has become a research focus of cancer treatment due to the non-invasiveness, spatio-temporal controllability, and effectiveness repeated treatment. Here, Au@MOF core-shell hybrids were designed constructed by layer-by-layer method, thickness MOF shell can be adjusted controlling coordination reaction between layers. Au nanorod cores mainly produce PTT effect their strong absorbance at 650 nm. The porphyrin ligand in convert O2 into 1O2 under light...

Although targeted delivery of nanoparticulate vaccines to dendritic cells (DCs) holds tremendous potential, it still faces insufficient internalization and endosome degradation via the receptor-mediated endocytosis pathway. Inspired by advantages CXC-chemokine receptor type 4 (CXCR4)-mediated macropinocytosis in DCs, a multifunctional vaccine is constructed based on reactive oxygen species (ROS)-responsive core macropinocytosis-inducing peptide-fused cancer membrane shell, allowing direct...
Surface patterns of well-defined nanostructures play important roles in fabrication optoelectronic devices and applications catalysis biology. In this paper, the diporphyrin honeycomb film, composed titanium dioxide, protoporphyrin IX, hemin (TiO2/PPIX/Hem), was synthesized using a dewetting technique with polystyrene (PS) monolayer as template.
