- Synthesis of poly(1,10-phenanthroline-5,6-diyl)s having a π-stacked, helical conformation
-
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.

- APPLICATION OF 2,9-DI-SEC-BUTYL-1,10-PHENANTHROLINE AS A GLIOBLASTOMA TUMOR CHEMOTHERAPY
-
A method of inhibiting cancer cell growth is provided. In some versions, the method includes exposing lung cancer cells or glioma cells to 2,9-di-sec-butyl-1,10-phenanthroline (SBP) or derivatives of SBP in an amount effective to inhibit glioma cell growth. Also, a method of treating a lung cancer or a glioma tumor in a subject in need of such treatment is provided. The method includes administering SBP or derivatives of SBP to the subject in an amount effective to treat the lung cancer or glioma tumor. For either method, the method can further include exposing or administering pseudo five coordinate gold(III) complexes of SBP derivatives.

- Asymmetric ruthenium-catalyzed hydrogenation of 2- and 2,9-substituted 1,10-phenanthrolines
-
A 'Phen'atic: The title reaction proceeds in the presence of the chiral cationic ruthenium diamine catalyst (R,R)-1 (Tf=trifluoromethanesulfonyl, Ts=4-toluenesulfonyl). Both chiral 1,2,3,4-tetrahydro- and 1,2,3,4,7,8,9,10- octahydro-1,10- phenanthroline derivatives could be obtained in high yields with excellent enantio- and diastereoselectivity. Copyright

- Self-assembling of n-type semiconductor tri(phenanthrolino) hexaazatriphenylenes with a large aromatic core
-
Large disk-shaped aromatic tri(phenanthrolino)hexaazalriphenylenes 5a, 5b, and 5c with six butyl, dodecyl, and 4-octylphenyl groups, respectively, were self-assembled both in solution and film state to form one-dimensional aggregates. Their n-type semiconducting nature was indicated from CV measurement, in which the first reduction potentials were evaluated at around -1.7 V (vs Fc/Fc+) in dichloromethane.

- Substituted 1,10-phenanthroline-5,6-diamines and their extension to soluble, acetylenic pyrazinophenanthrolines
-
2,9-Disubstituted and 3,8-disubstituted 1,10-phenanthrolines have been converted to the respective 5,6-diamines in three steps. The new heterocycles have been employed in condensation reactions with a protected 1,2-dialkynyl-1,2-dione to afford solubility-improved, acetylenic pyrazinophenanthrolines (pyzphen). In an initial study, the synthetic scope of these novel acetylenic ligands is evaluated. Georg Thieme Verlag Stuttgart.

- Synthesis and antimycoplasmal activity of 2,2'-bipyridyl analogues. Part III. 1,10-Phenanthrolines and 2,2'-bipyridyls
-
The synthesis and antimycoplasmal activity in the presence of copper of a series of 1,10-phenanthrolines and 2,2'-bipyridyls are presented. It is shown that the unsubstituted parent compounds have the lowest activity. Introduction of substituents in one or both of the orthopositions raises the activity, alkyl groups having the most pronounced activity enhancing effect. Generally 1,10-phenanthrolines are 2-4 times more active than corresponding 2,2'-bipyridyls.

- DIRECT SYNTHESIS OF DISUBSTITUTED AROMATIC POLYIMINE CHELATES
-
The reaction of an alkyl- or aryl-lithium with 1,10-phenanthroline followed by hydrolysis and rearomatisation with manganese dioxide gives good yields of the 2,9-disubstituted product.This synthetic method has been extended to other polyimines such as 2,2'-bipyridine, 2,2',6',2''-terpyridine and 1,8-naphtyridine.
