A new selective medium (PC agar) for the isolation of Pseudomonas aeruginosa was developed, consisting of 30 micrograms of 9-chloro-9-[4-(diethylamino)phenyl]-9,10-dihydro-10-phenylacridine hydrochloride (C-390) per ml and 30 micrograms of phenanthroline per ml in Columbia agar. PC agar was superior to phenanthroline, C-390, acetamide, and cetrimide agars for the selective growth of P. aeruginosa.

A concise synthetic protocol for aryl functionalized phenanthrolines has been developed. It was demonstrated that 3,8-diphenyl-1,10-phenanthroline (7a) is competent in promoting transition-metal-free direct arylation and 2,3,8,9-tetraphenyl-1,10-phenanthroline (8a) is a highly efficient ligand in the in situ Pd-catalysed Heck reaction.

Two Anderson-type heteropolyanion-supported copper phenanthroline redox couples have been successfully introduced into dye-sensitized solar cells, which can significantly increase the short-circuit photocurrent, open-circuit voltage and the conversion efficiency by 2.2 times, 26.8% and 3.93 times respectively, compared to the pristine copper phenanthroline redox couple.

Condensation of 5,6-diamino-4,7-phenanthroline with glyoxal provides 1,4,5,12-tetraazatriphenylene in quantitative yield. This procedure avoids the 50% loss of product inherent in previous methods. Derivatives were also prepared by using alpha-dicarbonyl compounds other than glyoxal. Additional derivatives were prepared from 1,4,5,12-tetraazatriphenylene-2,3-dicarbonitrile, produced by condensa...

New ytterbium (III) compounds with β-diketones (2,7-dimethyl-octene-1-dione-3,5 and 2,6-dimethylheptene-1-dione-3,5) their derivatives phenanthroline have been synthesized. The composition chemical structure of the obtained complexes determined by several Phy­sico-chemical investigations. It has shown, that Yb ion coordinates three ligand molecules coordination sphere is supplemented two mole­c...

New fused pyrrolo-phenanthroline type derivatives were synthesized, in two steps, from 1,10-phenanthroline and evaluated for antimicrobial activity fluorescence properties. Our synthetic approach involved a 3+2 dipolarcycloaddition of some selected N-substituted 1,10-phenanthrolin-1-ium ylides, (m)ethoxycarbonyl cyano (1,2-di)substituted acetylenes alkenes, respectively. The structures compound...

The synthesis and characterization of eight new bis-cyclometalated compounds [M(ptpy)2(N^N)]PF6 (ptpy=2-(p-tolyl)pyridinato; N^N=5-chloro-1,10-phenanthroline: M=Rh, 1; M=Ir, 2); N^N=5-methyl-1,10-phenanthroline: 3; 4; N^N=4,4’-diphenyl-2,2’-bipyridine: 5; 6; N^N=4,4’-diamino-2,2’-bipyridine: 7; 8) are described. All were characterized by spectroscopic means. Additionally, the molecular structur...

Two series of bidentate polypyridine ligands, made of phenanthroline chelating subunits having substituted mono-and di-anthracenyl groups, and 1-methoxy-1-buten-3-yne at the 4 and 7-positions with the corresponding heteroleptic Ru(II) complex have been synthesized and characterized. The complex is formulated as [(Ru(L(1))(L(2))(NCS)(2))], (where L(1 )= 4-(9-dianthracenyl-10-(2,3-dimethylacrylic...

In the title dinuclear complex, [Ni(2)(C(8)H(7)O(2))(4)(C(12)H(8)N(2))(2)(H(2)O)], each Ni(II) atom is six-coordinated by three carboxylate O atoms from three 4-methyl-benzoate ligands, two N atoms from two 1,10-phenanthroline ligands, and one μ(2)-bridging aqua ligand. The dimeric complex is located on a crystallographic twofold axis and each Ni atom displays a distorted octa-hedral coordinati...
