一般描述
Chromium(III) acetylacetonate (Cr(acac)₃) is a high-purity (≥97%) coordination complex that appears as a purple to very dark purple powder or in chunk form. It is a stable, air-insensitive compound, soluble in non-polar organic solvents. Its high thermal stability and well-defined molecular structure make it an excellent precursor for synthesizing advanced materials. Cr(acac)₃ is especially valued for applications in catalysis, thin film deposition, and as a molecular probe in spectroscopic studies.

The incorporation of second-row transition metals into metal-organic frameworks could greatly improve the performance of these materials across a wide variety of applications due to the enhanced covalency, redox activity, and spin-orbit coupling of late-row metals relative to their first-row

Nuclear magnetic resonance spectroscopy relies on using multiple excitation pulses to create multiple quantum coherences that provide great specificity for chemical measurements. Coherent multidimensional spectroscopy (CMDS) is the optical analogue of NMR. Current CMDS methods use three excitation pulses and

Nearly monodisperse lanthanide-doped magnetite nanoparticles were obtained by thermally decomposing a mixture of Fe(acac)(3) and Ln(acac)(3) (acac = acetylacetonate; Ln = Sm, Eu, Gd) in the presence of passivating surfactants. Magnetic studies revealed room-temperature ferromagnetic behaviors of these doped nanoparticles

A solution-processed vanadium oxide (s-VO(x)) anode buffer layer on an indium-tin-oxide (ITO) electrode was used instead of PEDOT:PSS for improving the stability and photovoltaic performance of the polymer solar cells (PSCs). The s-VO(x) layer was prepared by spin-coating a vanadyl

Current precious-metal-containing anticancer agents are mostly chelated with N-containing ligands and function by interacting with DNA. In the present study, Pd(acac)2, a Pd(II) complex containing four O-donor ligands, has been evaluated as an active anticancer agent. Pd(acac)2 showed no interaction
