SmI(2) serves as an effective promoter for the coupling of 1,10-phenanthroline with an epoxide to generate a new class of chiral, functionalized ligands that readily form complexes with metals. Structural studies of the resulting phenanthroline derivative and two of its metal complexes are reported.

Copper compounds with artificial metallo-nuclease (AMN) activity are mechanistically unique compared to established metallodrugs. Here, we describe the development of a new dinuclear copper AMN, Cu2-BPL-C6 (BPL-C6 = bis-1,10-phenanthroline-carbon-6), prepared using click chemistry that demonstrates site-specific DNA recognition with low micromolar cleavage activity. The BPL-C6 ligand was designed to force two redox-active copper centres-central for enhancing AMN activity-to bind DNA, via two phenanthroline ligands separated by an aliphatic linker.

Nine manganese(II) complexes with a series of non-steroidal anti-inflammatory drugs (namely sodium diclofenac, diflunisal, flufenamic acid, sodium meclofenamate, mefenamic acid, and tolfenamic acid) were prepared in the presence of diverse nitrogen donors, i.e., pyridine, 1,10-phenanthroline, 2,2'-bipyridine and neocuproine, as co-ligands and were characterized with spectroscopic techniques and single-crystal X-ray crystallography.

Regulating strategies for long persistent luminescence (LPL) are always in high demand. Herein, a series of coordination polymers (CPs) (SUST-Z1-Z4) are fabricated using 1,10-phenanthroline derivatives involving different substituents (─H, ─CH, ─Cl, and ─Br) as ligands, respectively. Crystallographic data demonstrate that these CPs adopt alternating arrangements of cadmium halide chains and π-conjugated ligands.

The chemical similarities between trivalent actinides [An(III)] and lanthanides [Ln(III)] present a significant challenge in differentiating and separating them, which is a key step toward closing the nuclear fuel cycle. However, the existing separation approaches commonly suffer from demerits such as inadequate separation factors, limited stripping efficiency, and undesired coextraction. In this study, a novel unsymmetrical phenanthroline-derived amide-triazine (Et-Tol-CyMe-ATPhen) extractant was first designed and then screened with theoretical computation.

This paper presents a copper(I)-catalyzed intramolecular tandem acylation/-arylation of methyl 2-[2-(2-bromophenyl)acetamido]benzoates for the synthesis of benzofuro[3,2-]quinolin-6(5)-ones under mild conditions. The combination of CuI, 1,10-phenanthroline, and KCO in DMSO was found to be the optimal reaction condition, producing the target products in high yields (84-99%) at 70 °C for 16 h. The tandem reaction was applicable to substrates bearing halo, electron-withdrawing, and electron-donating groups at their phenyl moieties with a broad substrate scope.
