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.

B09基于langmuir - blodgett技术开发了分子间相互作用可调的分子膜，用于分子ps和cat的集成。定制的两亲分子将在水-空气界面上排列，由此产生的二维膜将分别通过超分子相互作用（例如氢键）或通过光聚合（例如（甲基）丙烯酸酯）和缩聚形成共价交联而在机械和化学上稳定下来。交联Langmuir-Blodgett层的后功能化将用于引入分子PS和CAT单元（重点：HER和WOC），它们可以附着在两侧的其中一侧。膜的功能将从导电系统上的纯粹结构支撑发展到耦合光氧化还原反应的含ps膜。
