Self-regulating Photocatalytic Materials Based on pH-responsive Block Copolymers (B05+)

• Subject Area: Theoretical Chemistry: Molecules, Materials, Surfaces ; Polymer Materials
• Term: from 2018 to 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 364549901

The project develops photocatalytic materials where activity or accessibility of a catalytic center is controlled by external parameters such as pH value or temperature. This will ultimately lead to composites which provide optimum reaction conditions for prolonged periods. We will co-integrate Ru- or rylene-based photosensitizers and Pt- or Co-based catalysts into colloidal polymer models where changing environmental conditions lead to modification of swelling degree or charge density. These structural transitions will be described by theoretical modeling.
