One Stone, Three Birds: Design and Synthesis of "All-in-One" Nanoscale Mn-Porphyrin Coordination Polymers for Magnetic Resonance Imaging-Guided Synergistic Photodynamic-Sonodynamic Therapy.

Multifunctional nanomaterials with potential applications in both bioimaging and photodynamic-sonodynamic therapy have great advantages in cancer theranostic, but the design and preparation of "all-in-one" type of multifunctional nanomaterials with single component remains challenging. Herein the "all-in-one" type of Mn-PpIX (Protoporphyrin IX) coordination polymers (MnPPs) was reported as efficient nano-photo/sonosensitizers. The MnPPs had an average size of ∼ 110 nm.

Acetate-Decorated Tri-Ln(III)-Containing Antimonotungstates with a Tetrahedral {WO} Group as a Structure-Directing Template and Their Luminescence Properties.

Four acetate-decorated tri-Ln-substituted trimeric antimonotungstates (AMTs) Na{(WO)[Ln(HO)(Ac)(B-α-SbWO(OH))]}·50HO [Ln = Eu (), Dy (), Ho (), or Gd ()] were isolated by reaction of Na[B-α-SbWO]·19.5HO, NaWO·2HO, and Ln(NO)·6HO in a HAc/NaAc buffer solution. Interestingly, a tetrahedral {WO} group plays a significant structure-directing template role in the formation of their polyoxoanions.

Double-Oxalate-Bridging Tetralanthanide Containing Divacant Lindqvist Isopolytungstates with an Energy Transfer Mechanism and Luminous Color Adjustablility Through Eu/Tb Codoping.

A double-oxalate-bridging tetra-Gd containing divacant Lindqvist dimeric isopolytungtate Na[Gd(CO)(HO)(OH)WO]·30HO () was obtained based on the reaction of NaWO·2HO, HCO, and GdCl in aqueous solution. Its dimeric polyoxoanion is established by two divacant Lindqvist [WO] segments connected by a rectangular tetra-nuclearity [Gd(CO)(HO)(OH)] cluster. Notably, neighboring trinuclear [NaO(HO)] clusters are interconnected to construct a picturesque 1-D sinusoidal Na-O cluster chain.

Noncovalent phosphorylation of CoCr layered double hydroxide nanosheets with improved electrocatalytic activity for the oxygen evolution reaction.

Noncovalent phosphorylation of CoCr layered double hydroxides (LDHs) was successfully performed for the first time by blending CoCr LDHs with a precursor solution of P2O5 dissolved in isopropanol. The as-prepared material exhibits a higher oxygen evolution reaction electrocatalytic activity than those based on pristine CoCr LDHs and commercial RuO2.

Shape-control of CeF nanocrystals by doping polyoxometalates: syntheses, characterization and tunable photoluminescence.

A series of CeF3 nanocrystals with uniform morphologies have been synthesized by introducing various polyoxometalates as dopants and shape modifiers. The results indicate that the shape and photoluminescence of the CeF3 nanocrystals could be finely tuned by changing the component and amount of the polyoxometalates.

Synthesis and spectroscopic properties of silver-fluorescein co-doped phosphotungstate hollow spheres.

Herein, silver-fluorescein co-doped phosphotungstate hollow spheres have been successfully synthesized using a chemical precipitation method by introducing silver ions and fluorescein at room temperature. This hybrid nanomaterial possesses a uniform structure, exhibiting a strong emission spectrum with a peak centered at 517 nm. It is anticipated that silver and fluorescein as functionalized dopants for the phosphotungstate hollow sphere structure would provide this material with multiple properties.
