Synthesis and Properties of Covalently Linked Trichromophore Systems was written by Khan, Tamanna K.;Ravikanth, Mangalampalli. And the article was included in European Journal of Organic Chemistry in 2011.Formula: C47H36N4O The following contents are mentioned in the article:
Four covalently linked trichromophore systems containing a central boron dipyrromethene (BODIPY) unit connected to a porphyrin unit through the 3-position and a core-modified porphyrin or a porphyrin expanded through the 5-position were synthesized by treating 3-bromo-5-porphyrinyl BODIPY or 3-bromo-5-rubyrinyl BODIPY with the corresponding hydroxy porphyrin or hydroxy-expanded porphyrin in CHCl3 at 60 ¡ãC. The compounds are freely soluble in common organic solvents and confirmed by mass spectrometry and 1D and 2D NMR spectroscopy techniques. The absorption and electrochem. studies support weak ground-state interactions among the three chromophore units within the trichromophore systems. The fluorescence studies indicate that BODIPY emission is quenched to a significant degree in all trichromophore systems due to a transfer of energy to one or both macrocyclic units attached to the BODIPY chromophore. This study involved multiple reactions and reactants, such as 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5Formula: C47H36N4O).
4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5) belongs to catalyst ligands. Ligand design occupies a central place in organic synthesis and catalysis. It is clear that future advancements in metal complexes and their applications crucially depend on ligand design, whereas the ligand electronic, steric and topological properties provide numerous improvements to the reactivity and selectivity at the metal centers.Formula: C47H36N4O
