Article Synopsis
- A new electrochemical method was developed to create multilayer assemblies of coordination complexes on gold surfaces, using specific complexes ([Ru(tpySH)(2)](2+) and [Fe(tpySH)(2)](2+)) for surface attachment.
- Cyclic voltammetry revealed distinct oxidation processes for the complexes, indicating differences in their redox behavior when adsorbed on gold electrodes compared to their behavior in solution.
- The study demonstrated successful layer-by-layer growth of the assembly due to electrochemical formation of disulfide bonds, leading to stable films that maintained consistent electrical responses over multiple cycles.
Article Synopsis
- The study focuses on creating and analyzing two new bis-terdentate Ru(II) complexes, one with two CNC NHC ligands (Compound 1) and the other with one CNC ligand and a terpyridine ligand (Compound 2).
- X-ray crystal structures were determined, revealing that Compound 1 has a nearly perfect octahedral shape but does not luminesce at room temperature, while Compound 2 shows luminescence at both room temperature and at 77 K despite its slightly twisted geometry.
- The introduction of NHC ligands significantly increases the electronic density at the metal center, resulting in a lower oxidation potential compared to similar polypyridyl complexes.
