The Organic Photochemistry Group works in two complimentary research fields: (i) Organic synthesis – preparation of new photoactive compounds with designed optical properties, light-induced reactions, use of photolabile protecting groups; (ii) Molecular spectroscopy – steady-state and time-resolved absorbance and fluorescence. This allows the development of new compounds and materials on their base (functionalized dendrimers and polymers; metal, host-guest and intercalation complexes) with application as optical sensors and photoactive organometallic catalysts for environmental protection, labeling agents for nucleic acids and proteins, metal complexes for antimicrobial activity.
