CYSS2021 will be hosted online using Zoom. The poster session will follow a dual-format approach using a chat-platform and videoconference rooms.

Speaker

Prof. Oliver Wenger (University of Basel)

Description

This talk will focus on three different topics. In the first part, I will present recent results obtained by Mirjam Schreier, Xingwei Guo and Björn Pfund on photo-triggered hydrogen atom transfer (photo-HAT) between an iridium hydride complex and olefins.1 Whilst photoinduced electron transfer (PET) is very common for transition metal complexes, photo-HAT is rare.
In the second part, I will talk about unusually photostable ruthenium(II) complexes investigated by Lucius Schmid and Christoph Kerzig, and how these complexes (with their high triplet energies) are useful for photoredox and energy transfer catalysis.2
In the final part, I will tell about our latest adventures in the development diisocyanide complexes as Earth-abundant analogs of well-known ruthenium(II) polypyridines. This will include Jakob Bilger’s deep red molybdenum(0) emitter that he used for triplet-triplet annihilation upconversion,3 and some new first-row transition metal luminophores.
