Our group currently consists of Prof. Timo Repo, postdoctoral researchers, doctoral students, and undergratuate students, each working on their own individual yet interlocked research project in close collaboration with other members of our team.
Timo Repo received his PhD in 1997 from University of Helsinki under the guidance of Prof. Markku Leskelä. During 1998 - 2003 he worked at University of Helsinki, first as a postdoctoral researcher and then as an Academy researcher, the latter granted by Academy of Finland. In 2003, he was appointed as Academy research fellow by Academy of Finland. In July 2007 he was nominated as a professor of green chemistry at University of Helsinki. During his PhD studies and later career he has been actively collaborating with Prof. Bernhard Rieger in Technical University of Munich.
His research is focused on the development of inorganic/organometallic chemistry, green chemistry, homogeneous catalysis, especially catalyst development for major chemical transformations including oxidation, reduction, C-H activation, and C-C coupling applied for small molecule activation and biomass valorization.

My main focus in teaching and research is chemical crystallography, structural chemistry, and X-ray structure analysis, showing the influence of the structure in the solid state, but also in solution, on the chemical and physical properties. This covers a wide area of inorganic chemistry, organometallic chemistry, organic chemistry and supramolecular chemistry.
Since 1994 I’m a Docent for Crystallography at the University of Joensuu and in 2011 I was appointed as a Docent in Inorganic Chemistry at the University of Helsinki.

My research focuses on the liquid organic hydrogen carriers that could be used for transportation and storing of renewable energy.
My aim is to develop methods for environmental hydrogen production, preferably from water. Research is focusing on complex synthesis and their evaluation for water splitting properties (production of hydrogen and/or oxygen).
I am also known as great t-shirt designer and tea ceremonial leader at our research group.

My research work consists of two parts. One is aimed at searching for the reaction mechanism when catalyzing six carbon sugars, then exploring how the coal is formed via chemical reaction. The other is searching for the missing tool for biorefinery, chemicals and materials from renewable feedstock, namely lignin.

In my research I focus on the development of safe, sustainable and selective methods for oxidative dissolution and recovery of noble metals. The topic covers the coordination chemistry of gold and other noble metals.

My research is about synthesizing metal organic complexes, which are active for the selective oxidation of alcohols. These metal organic complexes are made from copper and a variety of Schiff base ligands. The aim is to combine new copper(I)-Schiff-base-complexes with reactants (TEMPO, organic base) to oxidize alcohols in a more selective and efficient way.

My studies focus on development of novel Frustrated Lewis Pairs concepts. The aim is to activate H-H bonds for development of novel metal based and particularly metal-free hydrogenation catalysis and hydrogen storage concepts.
I research the organocatalytic activation of CO2, and its subsequent capture by various amines into carbamates. These are then reacted with suitable trapping reagents, for example γ-brominated Michael acceptors, resulting in stable 2-oxazolidinones. I am interested in the use of strong neutral organic bases as catalysts, guanidines in particular.

Generally, my research area is metal-free activation of small molecules such as H2, H2O, and CO2 with frustrated Lewis pairs (FLPs). One possible application of such reactivity of FLPs is amplification of NMR signal by means of parahydrogen-induced polarization (PHIP). The latter can be observed through interaction of ansa-FLP with H2 that is enriched with p-H2 (parahydrogen), one of its spin isomers. PHIP results in increased by orders of magnitude NMR signal intensities of p-H2-originating 1H nuclei as well as other magnetically coupled nuclei, such as 13C, 15N, 31P, etc. Therefore, it has a potential as a tool for magnetic resonance (in vivo) imaging. I am currently focused on the design and synthesis of ansa-FLPs for this particular application.

My research is focused on the valorization of biomass towards valuable bulk chemicals. The aim is to develop integrated process for the efficient utilization of the whole lignocellulosic biomass (cellulose, hemicellulose and lignin).
