Octahedral Ru(II) polypyridyl complexes constitute a superb platform to devise photoactive triggers capable of delivering entire molecules in a reliable, fast, efficient and clean way. Ruthenium coordination chemistry opens the way to caging a wide range of molecules, such as amino acids, nucleotides, neurotransmitters, fluorescent probes and genetic inducers. Contrary to other phototriggers, these Ru-based caged compounds are active with visible light, and can be photolysed even at 532 nm (green), enabling the use of simple and inexpensive equipment. These compounds are also active in the two-photon regime, a property that extends their scope to systems where IR light must be used to achieve high precision and penetrability. The state of the art and the future of ruthenium polypyridyl phototriggers are discussed, and several new applications are presented.

An account of the performance of a modern and efficient approach to Density Functional Theory (DFT) for the prediction of the photophysical behavior of a series of Ru(II) and Os(II) complexes is given. The time-dependent-DFT method was used to interpret their electronic spectra. Two different types of compounds have been analyzed: (1) a complex undergoing a light induced isomerization of one of its coordination bonds; (2) an inorganic dyads expected to undergo intramolecular photoinduced electron transfer to form a charge separated (CS) sate. Besides the noticeable quantitative agreement between computed and experimental absorption spectra, our results allow to clarify, by first principles, both the nature of the excited states and the photochemical behavior of these complex systems, thus underlying the predictive character of the theoretical approach. RésuméNous rendons compte ici des performances d'une approche moderne et opérante de la théorie de la fonctionnelle de la densité (DFT) pour la prédiction du comportement photophysique de composés du ruthénium (II) et de l'osmium(II). Pour interpréter leurs propriétés d'absorption électronique, l'approche DFT dépendante du temps a été utilisée. Nous illustrons notre propos par l'analyse des deux systèmes suivants : (1) un complexe qui présente une isomérisation photo-induite de la liaison de coordination impliquant l'un de ses ligands ; (2) une molécule bipartite composée d'un complexe photosensibilisateur lié à un accepteur d'électron, conçue pour être le siège d'un transfert d'électron photo-induit conduisant à la formation d'un état de « charges séparées » (CS). Au-delà du remarquable accord quantitatif constaté entre les caractéristiques calculées et expérimentales des spectres d'absorption, nos résultats ont permis de clarifier, ab initio, la nature des états excités impliqués, illustrant ainsi les vertus prédictives de l'approche théorique employée.

“…A Figura 2 exemplifica duas formas de obtenção de um metalopolímero [25]: (1) no polímero já sintetizado, coordena-se o complexo metálico, e (2) o complexo metálico que contém os iniciadores (I) reage com o monômero iniciando a polimerização. Essas duas reações produzem metalopolímeros.…”

“…Muito progresso tem sido alcançado no desenvolvimento de metalopolímeros contendo o metal com o macroligante [25,26]. Entretanto, ainda se faz necessário que novas metodologias sejam estabelecidas para o preparo de ligantes funcionalizados tais como monômeros funcionalizados [27] e ligações destes aos metais.…”
