In the Coordination and Bioinorganic Physicochemistry Group thermal and photochemical reactivity of coordination compounds of transition metals is studied.
The main research areas are focused at correlations between electronic structures and thermal and photochemical reactivity of coordination compounds. Complexes containing transition metal ions from the first d-raw are of special interest, among them there are homoleptic, mixed-ligand and mixed-valence complexes. Studied photochemical and photophysical processes are of environmental and medical relevance – from photochemical transformations of coordination compounds present in the environment through homo- and heterogeneous photocatalytic systems capable of air and water detoxification to applications in photodynamic therapy and diagnosis (PDT, PDD).
The aim of our studies is elucidation of mechanisms of inorganic and bioinorganic reactions and modeling of selected chemical systems. These studies help to understand the role of transition metal compounds in the environment, involving such processes like photoinduced electron transfer, photosubstitution, etc. Heterogeneous semiconductor photocatalysts are optimized for their applications in water detoxification. Particularly important task is photosensitization of typical oxides (TiO2, ZnO, SnO2) towards visible light. Similar systems may show properties of chemical logic gates, switches and other systems suitable for information processing. Biomedical studies lead to synthesis and tests of new chemicals being promising candidates for drugs and indicators in PDT and PDD. Also this field of activity requires extensive mechanistic investigations (generation of reactive oxygen species, interactions with nucleic acids, etc.).
