A phenanthroline analogue of Tröger's base as bridging ligand in the synthesis of a bimetallic ruthenium (II) complex
Complexation of a Phenanthroline analogue of Troger's Base 2 to Ru(Bpy)22+ units results in the formation of a dinuclear complex 3. The spectroscopic data in absorption and emission indicate that the resulting dinuclear compound 3 behaves as two independent monometallic Ru(II) complexes.info:eu-repo/semantics/publishe
The diastereoisomeric forms of a mononuclear Ru(II) complex bearing a bis-phenanthroline Tröger's base analogue
The synthesis of a novel completely asymmetric mononuclear complex of ruthenium(II) bearing a chiral bis-phenanthroline Trögerâs base ligand 1 (TBphen2) is reported. The diastereoisomeric forms of [Ru(phen)2TBphen2]2+ (ÎS/ÎR=rac-2a and ÎS/ÎR=rac-2b) were separated through crystallization. A complete structure elucidation of the diastereoisomers in solution, including chirality assignment, was achieved by 1D and 2D NMR techniques. Photophysical characterization revealed no significant differences in the emission properties of rac-2a and rac-2b that closely resemble those of [Ru(phen)3]2+. Structural elucidation by 1H NMR and stereochemistry assignment of the diastereoisomeric forms of a novel Ru(II) complex bearing a chiral âVâ-shaped TrogĂ«râs base is reportedinfo:eu-repo/semantics/publishe
