“…On the other hand, several reports on the general, flexible and modular ruthenium(II) complexes synthesis of type cis-Ru(N,N) 2 X 2 (where N,N is a dinitrogenated ligand and X is an halide such as chloride) conclude that the electronic effects produced by the ligands nature and coordination position are fundamental to control their electrochemical properties [16][17][18][19]. In addition, numerous studies on electron transfer and transport processes in solar cells based on TiO 2 with ruthenium (II) complexes have demonstrated successful results in energy conversion [16,20].…”

In this article we study the anchoring of cis-[Ru(bpyC 4 pyr)(CO) 2 (CH 3 CN) 2 ] 2+ , cis-[Ru(bpy) 2 (CO) 2 ] 2+ and cis-[Ru(bpyac)(CO) 2 Cl 2 ], onto nanoporous TiO 2 employing electropolymerization, electrostatic interaction and chemical bonding. Also, the [Re(bpyac)(CO) 3 Cl] rhenium(I) complex for chemical anchorage was analyzed. The characterization of TiO 2 /Ru(II) and TiO 2 /Re(I) nanocomposite films was performed by field emission scanning electron microscopy (FESEM), electron dispersive X-ray spectroscopy (EDS) and Raman spectroscopy. In addition, for the more stable nanocomposites obtained, the catalytic properties (solar energy conversion and CO 2 reduction) were evaluated. The efficiency improvement in redox process derived from the (photo)electrochemical evidence indicates that modified nanoporous TiO 2 structures enhance the rate of charge transfer reactions.

Pincer ligands are interesting chelating agents due to their high ability to motivate the metal ion characteristics leading to diverse types of applications. These ligands and their metal complexes are smart materials which have a great impact in the development of diverse applications helped alot in the advancement of the field of coordination chemistry. In homogenous catalytic transformations, pincer ligands improved the chemical and thermal stability that serve to minimize the leaching of the metal during the catalytic cycle. Also, they offered the ability to fine‐tune the electronic properties for the metal center, thereby increasing the scope of their coordination chemistry and applications especially the pincer ligands comprising s‐triazine core. This review discusses some of the general synthetic protocols of these s‐triazine pincer ligands and their metal complexes with various applications in different fields. In addition, their structural diversity and the ligand coordination behaviors with different metal ions were also explored.

“…Parenthetically, the peek current of the ruthenium polypyridyl complexes is in the order of microamperes. [51][52][53][54][55] The electrochemical behaviour of the DPC ligand includes the oxidation of DPC to DPCO, and then the DPCO oxidises to DPCDO with a potential of around 0.83 (V) and 1.5 (V), respectively 31 (ESI, Fig. S13 †).…”
