We present luminescent liquid-crystalline neodymium(III) complexes that contain three β-diketonate ligands and a mesogenic 1,10-phenanthroline ligand. Mesomorphism, including a nematic phase--very rare in lanthanide systems--is driven by the highly anisometric phenanthroline.

Self-assembled nanohybrids of a 1,10-phenanthroline derivative and Au nanoparticles exhibit different optoelectronic properties, as a consequence of the different arrangements of the nanoparticles on the surface of the different-sized phenanthroline scaffolds.

Objectives Due to the rapid increased drug resistance to Plasmodium parasites, an urgent need to achieve new antiplasmodial drugs is felt. Therefore, in this study, the new synthetic phenanthroline derivatives were synthesized with antiplasmodial activity. Materials and Methods A series of 1,10-phenanthroline derivatives containing amino-alcohol and amino-ether substituents were synthesized v...

The alcohol dehydrogenase crystallized from horse liver contains 2 atoms of zinc per molecule and the activity of this enzyme is inhibited by metal-binding agents (1, 2). The inhibition of liver alcohol dehydrogenase by one of these agents, 1, IO-phenanthroline, differs from that which is observed when the alcohol dehydrogenase isolated from yeast is exposed to 1, lo-phenanthroline (3). The liv...

The activation of aryl iodides and bromides by Cu(0)/1,10-phenanthroline in acetonitrile (S) generates Cu(I)(phenanthroline)S(2)(+) which can be a catalyst for cross-coupling reactions.

In the title complex, [Co(NCS)(2)(C(16)H(16)N(2)O(2))], the Co(II) ion is coordinated by two N atoms from one 2,9-dieth-oxy-1,10-phenanthroline ligand and two N atoms from two different thio-cyanate ligands in a distorted tetra-hedral environment. The Co-N bonds involving the thio-cyanate ligands are significantly shorter than the other two Co-N bonds. The atoms of one of the eth-oxy groups are...

The asymmetric unit of the title Cd(II) compound, [Cd(N(3))(2)(C(12)H(8)N(2))](n), contains a Cd(II) atom, located on a twofold axis passing through the middle of the phenanthroline mol-ecule, one azide ion and half of a 1,10-phenanthroline mol-ecule. The Cd(II) atom exhibits a distorted octa-hedral coordin-ation including one chelating 1,10-phenanthroline ligand and four azide ligands. The cry...

We have determined that the restriction endonuclease Eco RI contains 1.0 +/- 0.1 eq of zinc/monomeric enzyme. DNA cleavage by Eco RI is inhibited by ortho-phenanthroline after preincubation of the enzyme with the chelating agent. A similar inhibition by the nonchelating meta-phenanthroline is not seen. The sensitivity of the inhibition by the neutral ligand ortho-phenanthroline to preincubation...

A series of [Re(5-R-phen)(CO)3(X)]0/+, where phen = 1,10-phenanthroline, R H, CN, COOH, COONH2, and X Cl or pyridine, was prepared characterized by elemental analyses, NMR, Vis/UV, emission cyclic voltammetry. The complexes absorb in the near-ultraviolet region spectrum, emit between 550 600 nm with lifetimes 150 500 ns, undergo irreversible oxidation at 1.45 V a reversible reduction 1,10-phena...
