WG2 Device integration will immobilize hydrogen- and oxygen-evolving supramolecular photocatalysts (SPCs) developed in WG1 on large-surface area transparent conducting oxides and semiconductors as well as in membranes. Novel concepts for integration of SPCs into functional photocatalytically active electrodes will be derived and characterized experimentally.

Moreover, theoretical tools to describe electronic states induced upon binding and their correlation with photoinduced electron transfer and catalytic properties will be developed. To achieve proof-of-concept demonstration of a functional photocatalytic cell based on immobilized hydrogen- and oxygen-evolving SPCs, specific attachment chemistries will be employed to link SPCs onto transparent conducting oxide (TCO) electrode materials Theoretical chemistry will help to design systems with the correct energetic match between the positions of the valence/conduction bands of the electrode material and the HOMO/LUMOs levels of the SPC.

It will be researched how concepts known from material healing, e.g., the use of pH-reversibly-switchable connections between different functional subunits can be integrated into the molecular-semiconductor framework of photocatalytically active cells. Such concepts shall enable the controlled exchange of molecular components within the functional device, which might be particularly prone to chemical degradation, and thereby significantly prolong the lifetime of the devices.
