Photocatalytic Molecular Membranes via the Langmuir-Blodgett Technique (B09)

• Subject Area: Polymer Materials ; Physical Chemistry of Molecules, Liquids and Interfaces, Biophysical Chemistry
• Term: since 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 364549901

B09 develops thin molecular membranes with tunable intermolecular interactions for the integration of molecular PSs and CATs, based on the Langmuir-Blodgett-technology. Tailor-made amphiphiles will be aligned at the water-air-interface and the resulting two-dimensional membranes will be mechanically and chemically stabilized by supramolecular interactions (e.g., hydrogen-bonds) or covalently cross-linked by photopolymerization (of, e.g., (meth)acrylates) and polycondensations, respectively. Post-functionalization of the cross-linked Langmuir-Blodgett layers will be used to introduce molecular PS and CAT units (focus: HER and WOC), which can be attached to one of the two sides. The function of the membranes will be developed from purely structural supports over conductive systems to PS-containing membranes for coupled photoredox-reactions.
