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

Though recently Ir(III) complexes have attracted much interest in electrochemiluminescent (ECL) analysis due to their high emission in various wavelengths, there were a few studies reported on its analytical applications. In this study, we evaluate the ECL from (pq)(2)Ir(acac) (pq

Two NbO-type MOFs based on ditopic pyridyl substituted diketonate ligands were reported. One exhibits a reversible SC-SC water encapsulation, while the other shows an interesting guest-driven luminescent property based on M(III) acetylacetonate (M = Eu and Fe) guest species.

Biscyclometalated iridium(III) complexes with an ancillary acetylacetone ligand, Ir(L)(2)(acac), (L = 2-(benzo[b]thiophen-2-yl)pyridine (btp), 1-phenylisoquinoline (piq), 2-phenylbenzothiazole (bt), 2-phenylpyridine (ppy), acac = deprotonated acetylacetone), demonstrate spectroscopic changes in their UV-Vis absorption and luminescent emission under acidic conditions. Such changes were found
