Article
In the last decades, the number of articles describing the synthesis, characterization and applications of ruthenium polypyridyl complexes has significantly increased. One of the reasons is their tuneable, outstanding luminescent properties. However, ruthenium polypyridyl complexes usually have no intrinsic selectivity towards cancer cells, making...
Article
The synthesis and characterization of two half-sandwich complexes of Ru(II) and Ir(III) with thiabendazole as ancillary ligand and their DNA binding ability were investigated using experimental and computational methods. 1H NMR and acid-base studies have shown that aquo-complexes are the reactive species. Kinetic studies show that both complexes bi...
Article
The importance of ion pairing in different fields of chemistry is widely recognized. In this work, we have synthesized a set of cationic p-cymene ruthenium complexes of general formula [(p-cym)Ru(L′)(κ2-O^N–L)]X (p-cym = p-cymene; L′ = N-methylimidazole (MeIm), N-ethylpiperidylimidazole (EpipIm), 1,3,5-triaza-7-phosphaadamantane (PTA); L = 2-(1H-be...
Article
Full-text available
A new family of neutral ruthenium(II) arene complexes of the type [Ru(η6-arene)X(κ2- O, N-L)] (η6-arene = p-cym, bz; X = Cl-, SCN-; HL1 = 2-(2'-hydroxyphenyl)benzimidazole, HL2 = 2-(2'-hydroxyphenyl)benzothiazole) has been synthesized and characterized. The cytotoxic activity of the Ru(II) complexes was evaluated in several tumor cell lines (A549,...
Article
Full-text available
We describe the synthesis, characterization and biological and photocatalytic properties of two series of neutral Ir(III) biscyclometalated complexes of formula [Ir(C^N)2(N^O)], where the N^O ligands are 2‐(benzimidazolyl)phenolate‐N,O (L1, series a) and 2‐(benzothiazolyl)phenolate‐N,O (L2, series b), and the C^N ligands are 2‐(phenyl)pyridinate or...
Presentation
Biscyclometallated Ir(III) complexes have great photophysical properties, which make them uniques for their use as PS in PDT. We are looking for water-soluble complexes, whose absorption spectrum extends to >600 nm.
Article
A new family of heteroleptic biscyclometalated IrIII complexes with formula [Ir(C^N)2(N^N)]Cl, where (C^N) = 2‐phenylpyridinate and (N^N) = 2,2'‐dipyridylamine or N‐benzylated‐2,2'‐dipyridylamine, have been synthesized, characterized and successfully used as photosensitizers in the catalytic photooxidation of an array of dialkyl, dibenzyl, alkylary...
Article
A series of bis-cyclometalated iridium(III) complexes incorporating imidazole-based arylazole N^N ligands is reported and their use as electroluminescent materials in light-emitting electrochemical cell (LEC) devices is investigated. LECs performance is determined by the nature of the emitting state (³MLCT/³LLCT vs ³LC) and the electrochemical stab...
Article
This work describes the preparation of high-performance hybrid luminescent aramids (aromatic polyamides). The new hybrid aramids are based on the commercial MPIA (poly(m-phenylene isophthalamide) and possess structural units bearing iridium(III) fragments which are responsible for the luminescent behavior. The aramids were casted into films, which...

Anticancer activity and mechanistic insights of new Ru(II) half-sandwich complexes with hydroxiphenylbenzoazole ligands
Article
The complex [(η6-p-cymene)Ru(OH2)(κ2-N,N-HL1)](OTf)2 (HL1 = 2-pyridin-2-yl-1H-benzimidazole), [2c](OTf)2, undergoes easy deprotonation of the N–H group at physiological pH, producing [(η6-p-cymene)Ru(OH2)(κ2-N,N-L1)]+, [2c′]+, prone to dimerization both in solution and in the solid state. X-ray measurements on [2c′]BF4 have shown that dimer units a...
Article
The ligands 2-pyridin-2-yl-1H-benzimidazole (HL(1)), 1-methyl-2-pyridin-2-ylbenzimidazole (HL(2)), and 2-(1H-imidazol-2-yl)pyridine (HL(3)) and the proligand 2-phenyl-1H-benzimidazole (HL(4)) have been used to prepare five different types of new ruthenium(II) arene compounds: (i) monocationic complexes with the general formula [(η(6)-arene)RuCl(κ(2...
Article
The synthesis and full characterization of the new aqua-complex [(η(6)-p-cymene)Ru(OH2)(κ(2)-N,N-2-pydaT)](BF4)2, [2](BF4)2, and the nucleobase derivative [(η(6)-p-cymene)Ru(9-MeG)(κ(2)-N,N-2-pydaT)](BF4)2, [4](PF6)2, where 2-pydaT = 2,4-diamino-6-(2-pyridyl)-1,3,5-triazine and 9-MeG = 9-methylguanine, are reported here. The crystal structures of b...

Archived project
The aim of the project was to synthesize a battery of complexes, characterize them and study their properties and applications, specially their structure-activity relationships.
Project
Our aim is to find organometallic phosphorescent complexes able to produce singlet oxygen when they are light activated. Moreover, our intention is red-shift the absorption to irradiate in the NIR area.
