Abstract
\nRuthenium(II) polypyridine complexes are widely known class of luminophores with diverse applications ranging from lighting and solar energy conversion to phototherapy and synthetic photochemistry. The low-spin 4d6 valence electron configuration of RuII combined with energetically low-lying \uf070-antibonding orbitals on the polypyridine ligands are the key to the favorable photophysical and photochemical properties of this compound class. Mo0 is isoelectronic to RuII and can be stabilized by diisocyanide chelate ligands, 1,2 resulting in complexes that exhibit similar metal-to-ligand charge transfer (MLCT) luminescence and photo-reactivity. 3,4 The photophysical properties and photochemical applications of new Mo0 and Cr0 diisocyanide complexes will be discussed against the background of related research on photoactive FeII complexes.5,6

Biography
\nOliver S. Wenger received a Ph. D. degree from University of Bern (Switzerland) in 2002. After postdoctoral stays at Caltech (with Harry B. Gray) and University of Strasbourg (with Jean-Pierre Sauvage), he became assistant professor at University of Geneva in 2006. In 2009, he became associate professor at University of G\u00f6ttingen (Germany) and in 2012, he moved to the University of Basel (Switzerland) where he was promoted to full professor in 2018.<\/p>\n","protected":false},"excerpt":{"rendered":"
