Novel near-infrared BODIPY-cyclodextrin complexes for photodynamic therapy.

To meet the requirements of diagnosis and treatment, photodynamic therapy (PDT) is a promising cancer treatment with less side-effect. A series of novel BODIPY complexes (BODIPY-CDs) served as PDT agents were first reported to enhance the biocompatibility and water solubility of BODIPY matrix through the click reaction of alkynyl-containing BODIPY and azide-modified cyclodextrin (CD). BODIPY-CDs possessed superior water solubility due to the introduction of CD and their fluorescence emission apparently redshifted (>90 nm) on account of triazole units as the linkers compared to alkynyl-containing BODIPY.

Two cases of Kawasaki disease: Clinical characteristics and onset of fever and gastrointestinal symptoms.

Background: Kawasaki disease (KD) is a prevalent form of systemic vasculitis that can damage various organs and systems in children. Typical KD is not difficult to diagnose in clinical practice. In recent years, it has been shown that an increasing number of children do not satisfy the diagnostic criteria for typical KD.

The Z-scheme transfer of photogenerated electrons for CO photocatalytic reduction over g-ZnO/2H-MoS heterostructure.

Effective separation of the photogenerated electrons and holes is critical to improve photocatalytic efficiency. To achieve this, we design a Z-scheme g-ZnO/2H-MoS heterostructure to spatially separate the photogenerated carriers promoting the reduction of CO on the surface of the heterostructure, through density functional theory (DFT) calculations. The g-ZnO/2H-MoS heterostructure has a narrow band gap, which is beneficial to speed up the transport of carriers.

Cobalt-based ZIF coordinated hybrids with defective TiO for boosting visible light-driven photo-Fenton-like degradation of bisphenol A.

Designing heterostructure of photocatalyst as an efficient approach to boost visible light-driven photocatalytic degradation, we prepared a series of cobalt-based ZIF coordinated with defective TiO, denoted as B-TiO@ZIF-67 composites, through wrapping defective B-TiO on ZIF-67 for promoting photocatalytic degradation efficiency of biphenyl A. The B-TiO@ZIF-67 composites displayed superior photocatalytic performance to pure TiO or ZIF-67 because of faster separation of photogenerated charge carriers and more suitable redox potentials. Such a novel photo-Fenton-like system composed of B-TiO@ZIF-67/HO/visible light accelerated the peroxidative degradation of biphenyl An up to a removal efficiency of 95.

Two-Dimensional Imine-Linked Covalent Organic Frameworks as a Platform for Selective Oxidation of Olefins.

Two-dimensional imine-linked covalent organic frameworks with hydroxyl groups, TAPT-DHTA-COF and TAPT-DHTA-COF, were respectively constructed by the condensation of 1,3,5-tris-(4-aminophenyl)triazine and 2,5-dihydroxyl-terephthalaldehyde under solvothermal and reflux conditions. Both COFs possess excellent thermal stability and a similar eclipsed stacking structure verified by XRD patterns. However, TAPT-DHTA-COF presented a larger surface area (2238 m/g) and higher crystallinity than TAPT-DHTA-COF.
