OnderzoekMolecular Inorganic Chemistry - Browne group


Welcome to the research group of Prof Wesley R. Browne (Chair of Molecular Inorganic Chemistry)

Functional molecular materials and Catalytic Systems which is, since Jan 2015 part of the research unit Molecular Inorganic Chemistry.

The group's research activities include oxidation catalysis and functional molecular based materials and encompasses key expertise in electrochemistry and spectroscopy.

Examples of research carried out by the group in analytical spectroscopy, catalysis and materials are:

Fully reversible inorganic photochromic switch.

Duenpen Unjaroen (PhD student) together with Hans Kasper (Bachelor research student) have developed a fully reversible photochromic switch which is based solely on metal centred photochemistry - i.e. reversible photoinduced ligand dissociation. This new switch is based on a ruthenium(II) complex of a ligand with a long history in Groningen - MeN4Py (1,1-di(pyridin-2-yl)-N,N’-bis(pyridin-2-yl-methyl)-ethan-1-amine) and is better known as a ligand for iron(II) based oxidation catalysis.

New high quantum yield blue emitter s for application in Liquid Scintillator Technologies. In an upcoming paper, the development of a new class of blue emitters based on cheap and scalable syntheses of boron-1,2,4-triazoles will be described. These fluorophores are being evaulated for use in liquid scintillators for radiation detection as part of a cooperation between the Browne group and the team at INCAS3 lead by Dr Heinrich Wörtche.
