Welcome to the Homepage of the Hohloch Research Group.

We are interested in the synthesis of new, functional organometallic compounds und their applications in chemical and physical processes. Special emphasis is laid on the connection between the electronic and spectroscopic properties of a metal complex with its general reactivity. Understanding this interplay enables us to design tailor made metal complexes for a plethora of applications, including small molecule activation, single molecule magnetism and catalysis. To reach these goals, focus is put especially on the use of "non-classical" N-heterocyclic carbenes, such as cyclic alkyl amino carbenes (CAACs) and mesoionic carbenes (MICs). Another class of ligands that will be extensively used in our research will be macrocyclic ligands, including Tetramethyltetraazaannulene (TMTAA) or Norcorroles. On the metal side, we plan to focus on 3d transition metals (Sc - Zn) as well ason the lanthanides (La - Lu).

Interested in a bachelor, master or Ph.D. thesis? We are always searching for highly motivated chemists to enrich and enlarge our group. Just mail "the boss".



New paper accepted in Organometallics focussing on the reactivity and stability of high valent molybdenum NHC complexes.

Thanks to Marc, Fabian and Roland for all your efforts and the energy you have put into this project.

A link to the manuscript is about to follow.

The article will also be highlighted as a Supplementory Cover Image in one of the upcoming issues of Organometallics. Well done!

15.09.2019 Fabian attended the Wissenschaftsforum in Aachen presenting a Poster on the reactivity of lanthanum complexes with priamry and tertiary phosphines. Thank you for this amazing work and for spreading our chemistry around Germany and the World.

New paper online in Dalton Transactions focussing on the use of mesoionic carbenes in early transition metal chemistry.

Thanks to Marc, Fabian, Roland, Christoph and Adam for the wonderful collaboration and the effort you have put into this work.
