چکیده
5,6-Dibromo-1,10-phenanthroline and 2,9-di-n-butyl-5,6-dibromo-1,10-phenanthroline were polymerized using a Ni catalyst to afford helical polymers in which the phenanthroline moieties are densely stacked on top of each other. Polymerization of the latter monomer using a chiral catalyst led to a preferred-handed helix. This is the first Ni-catalyzed helix-sense-selective polymerization of aromatic compounds.

Synthesis and antiplasmodial activity of novel phenanthroline derivatives: An in vivo study
Objective(s): 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...

In the title compound, {[Co(C9H4N2O4)(C12H8N2)(H2O)2]·1.5H2O} n , the Co(II) atom is hexa-coordinated by one N atom and one O atom from two symmetry-related 1H-benzimidazole-5,6-dicarboxyl-ate ligands, two N atoms from one 1,10-phenanthroline ligand (phen) and two water mol-ecules. The dihedral angle between the 1H-benzimidazole-5,6-dicarboxyl-ate and 1,10-phenanthroline ligands is 74.41 (4)°. ...
متن کاملA chiral π-stacked vinyl polymer emitting white circularly polarized light.
An optically active, π-stacked poly[2,7-bis(4-tert-butylphenyl)dibenzofulvene] having a preferred-handed helical conformation was synthesized by anionic polymerization. A thin film sample of the polymer exhibited broad-band white circularly polarized light (CPL) emission on photo excitation.
متن کامل5,6-Dimethyl-1,10-phenanthroline
In the title compound, C14H12N2, the N⋯N distance is 2.719 (1) Å. The N-C-C-N torsion angle [0.9 (1)°] is close to the ideal value of 0° as expected. Bond lengths and angles are consistent with those observed for [1,10]phenanthroline and coordinated 5,6 dimeth-yl[1,10]phenanthroline. In the crystal, C-H⋯N hydrogen bonds link the mol-ecules into C(4) chains running parallel to the b axis. Weak π...

In the title compound, C12H6N2O2·C2H5OH, the mol-ecule of the 1,10-phenanthroline-5,6-dione is approximately planar, with a maximum deviation of 0.051 (1) Å. In the crystal, mol-ecules are linked by O-H⋯N and weak C-H⋯O hydrogen bonds, forming supra-molecular chains propagating along [110]. π-π stacking inter-actions are observed between the pyridine rings of neighbouring chains, the centroid-c...
