We report the synthesis and characterization of two novel tetra-cationic porphyrins, containing Pt(II) or Pd(II) polypyridyl complexes attached at peripheral position N4-macrocycle. Compounds were characterized through elemental analysis, molar conductivity, cyclic voltammetry, spectroscopy analysis. Photophysical photobiological parameters also evaluated. Also, binding capacity each porphyrin with human serum albumin (HSA) was determined by UV-Vis, steady-state, time-resolved fluorescence...
The use of dyes as sensitizing agents to increase semiconductor activity is a strategy already adopted in the field heterogeneous photocatalysis, but compounds applied are noble metal-based and sometimes difficult synthesize, which make it more expensive. In this work, was discovered that methylene blue can perform such an effect on iron molybdate functionalized with peroxo groups surface. This material, called MoOxoFe, tested together its analogue MoFe (produced without H2O2 synthesis)...
Glioblastoma (GBM) is the most common primary brain cancer in adults. Despite remarkable advancements recent years realm of diagnosis and therapy, regrettably, GBM remains lethal form cancer. In this view, fascinating area nanotechnology has emerged as an innovative strategy for developing novel nanomaterials nanomedicine, such artificial enzymes, termed nanozymes, with intrinsic enzyme-like activities. Therefore, study reports first time design, synthesis, extensive characterization...
Exploring photophysical/ROS species of Pd(<sc>ii</sc>)-porphyrins.
Methane conversion to valuable chemicals is a highly challenging and desirable reaction. Photocatalysis clean pathway drive this chemical reaction, avoiding the high temperature pressure of syngas process. Titanium dioxide, being most used photocatalyst, presents challenges in controlling oxidation process, which believed depend on metal sites its surface that function as heterojunctions. Herein, we supported different metals TiO2 evaluated their activity methane photooxidation reactions. We...
The photophysical properties of two<italic>meso–trans</italic>-A<sub>2</sub>B-type corroles containing phenyl or pyrenyl units were reported in this study. TD-DFT calculations and electrochemical analysis conducted to better understand the corrole molecular structures.
A commercial niobium oxide was used to form a gelled material, which lyophilized producing novel polyoxoniobate catalyst (L-AmNbO) containing peroxo groups. The activity of this new assessed through oxidation reactions the cyclohexene. In presence L-AmNbO catalyst, cyclohexene with H2O2 reached 90% conversion after 12 h at 75 °C, selectivity for 1,2-cyclohexanediol (∼ 50%). catalytic results and surface properties material indicated that it can be promising compounds applications in selective
