The first uranium(iii) charge separated ketyl radical complex, Tp*2U(OC·Ph2), has been isolated and characterized by infrared, 1H NMR, and electronic absorption spectroscopies, along with X-ray crystallography. Tp*2U(OC·Ph2) is a potent two-electron reductant towards N3Mes (Mes = 2,4,6-trimethylphenyl) and (2,2,6,6-tetramethyl-piperidin-1-yl)oxyl (TEMPO), with reducing equivalents derived from the metal centre and the redox-active benzophenone.

Using 1,4-diaminobenzene and 2-formylpyridine as simple building blocks results in a 1D ligand (rod, L2) to 2D (M4L4 grid, C1) to 3D (S4 symmetrical M4L6, C2) complexes upon sequential addition of Cu(i) and Fe(ii) ions. The complex C2 can be seen as the smallest possible pseudo-tetrahedron with S4 symmetry.

Microporous metal–organic frameworks (MOFs) represent a new family of microporous materials, offering potential applications in gas separation and storage, catalysis, and membranes. The engineering of hierarchical superstructured MOFs, i.e., fabricating mesopores in microporous frameworks during the crystallization stage is expected to serve a myriad of applications for molecular adsorption, drug delivery, and catalysis. However, MOFs with mesopores are rarely studied because of the lack of a simple, effective way to construct mesoscale cavities in the structures. Here, we report the use of a perturbation-assisted nanofusion technique to construct hierarchically superstructured MOFs. In particular, the mesopores in the MOF structure enabled the confinement of large dye species, resulting in fluorescent MOF materials, which can serve as a new type of ratiometric luminescent sensors for typical volatile organic compounds.

The oxidation of four benzylic alcohols employing hydrogen peroxide and TBHP as oxidants, catalyzed by an iron(iii) complex bearing a 14,28-[1,3-diiminoisoindolinato]phthalocyaninato (diiPc) ligand has been studied and found to proceed with good selectivity, high turnover numbers, and high turnover frequencies in the absence of organic solvents other than the substrates themselves.
