DNA-based nanomaterials are the subject of numerous researches. A series of modified nucleobases were synthesized either to construct a double helix where the natural Hbonded bases are replaced by metal-coordinated liganosides or to introduce a punctual modification inside a natural DNA structure. Thanks to their photophysical and photochemical properties, iridium(III) complexes are of increasing interest in

The novel catalysts of the type (I) are synthesized on a gram scale and applied in the hydrogenation of dehydroamino acids (II) and methylstilbene (IV). -(PASSAYS, J.; AYAD, T.; RATOVELOMANANA--VIDAL, V.; GAUMONT, A.-C.; JUBAULT, P.; LECLERC*, E.; Tetrahedron: Asymmetry 22 (2011) 5, 562-574, http://dx.
