Light-Up Carbon Dots for Copper (II) Detection by Aggregation-Induced Enhanced Strategy

Carbon dots have promising prospects for analytical and monitoring purposes but are greatly hindered by the aggregation-induced luminescence quenching owing to the π-π interaction or the non-radiation-excited radical complex formation....

Synthesis, Structures and Magnetic Properties of 1D Cu(II)-NIT Radical Complex

ABSTRACTAn 1D Cu(II) complex, which formula is [Cu(hfac)2NITpPy]n (1) (NITpPy = 2-(4-pyridyl)-4,4,5,5-tetra-methylimidazoline-1-oxyl-3-oxide, hfac = hexafluoroacetylacetonate) has been synthesized and characterized by single crystal X-ray diffraction. The complex 1 crystallizes in the triclinic pī space group. Two adjacent Cu(II) ions with different coordination modes are bridged by NITpPy to form a magnetic zig-zag chain. In the built chains, the Cu(II) ions located in the CuO4N2 coordination environment and the >N–O–Cu(II)- O–N< hetero-spin clusters of the CuO6 units are alternately arranged, which lead to two different Cu-NITpPy magnetic interactions. The fit parameters (J1 = −3.56 cm−1 and J2 = 0.46 cm−1) indicate an antiferromagnetic and ferromagnetic interactions in the complex 1.

Catalytic approach to in vivo metabolism of atractylenolide III using biomimetic iron–porphyrin complexes

In vivo oxygenation of atractylenolide III during the metabolism and in situ oxidation mechanism by an iron–porphyrin iron(iv)-oxo porphyrin π-cation–radical complex.

Characterization and reactivity study of non-heme high-valent iron–hydroxo complexes

One-electron oxidation of an FeIII–OH complex (1) results in the formation of a FeIII–OH ligand radical complex (2). Its reaction with (C6H5)3C˙ results in the formation of (C6H5)3COH, which is a functional mimic of compound II of cytochrome P450.
