New oligothienyl-imidazo-phenanthroline chromophores for NLO applications [PDF]

open access: yes, 2008
A new series of oligothienyl-imidazo-phenanthrolines 3 were synthesised in good to excellent yields by condensation of 5,6-phenantroline-dione 2 with formyl-thiophene derivatives 1 in the presence of ammonium acetate in glacial acetic acid.

Synthesis, characterization, photophysical studies and interaction with DNA of a new family Ru(II) Furyl- and Thienyl-imidazo-phenanthroline polypyridyl complexes [PDF]

open access: yes, 2012
A new family of Ru(II) polypyridyl complexes (C1 to C6) containing furyl- or thienyl-imidazo-phenanthroline ligands (4-6) were synthesized using microwave irradiation and characterized by elemental analysis, 1H-NMR, UV-vis absorption and fluorescence ...

Tertiary Alcohols as Radical Precursors for the Introduction of Tertiary Substituents into Heteroarenes [PDF]

open access: yes, 2019
Despite many recent advances in the radical alkylation of electron-deficient heteroarenes since the seminal reports by Minisci and co-workers, methods for the direct incorporation of tertiary alkyl substituents into nitrogen heteroarenes are limited ...

Iridium-Catalyzed Silylation of C-H Bonds in Unactivated Arenes: A Sterically Encumbered Phenanthroline Ligand Accelerates Catalysis. [PDF]

open access: yes, 2019
We report a new system for the silylation of aryl C-H bonds. The combination of [Ir(cod)(OMe)]2 and 2,9-Me2-phenanthroline (2,9-Me2-phen) catalyzes the silylation of arenes at lower temperatures and with faster rates than those reported previously, when ...

4,7-Phenanthroline

open access: yesActa Crystallographica Section E Structure Reports Online, 2001
The structure of 4,7-phenanthroline, C12H8N2, has been determined at 180 K. The molecular unit possesses pseudo-C2v point symmetry but does not possess crystallographic mirror symmetry. The mol­ecules form stacks approximately along the b direction, with mol­ecules in adjacent stacks forming an interplane angle of ca 54°.
