Noble Metal-free Photosensitizer-Catalyst Hybrids for Photocatalytic Hydrogen Generation under Visible Light (A02)

该项目旨在合成、表征和应用无贵金属、高活性可见光驱动的分子HER光催化剂。将研究通过将作为可见光光敏剂的π-共轭噻吩并苯共价连接到作为HER催化剂的铁氢化酶激发的二铁络合物来开发共价PS-CAT二联体。在铁配位环境中的化学修饰用于优化催化活性。作为替代催化剂模型，分子硫化钼将共价连接到合适的噻吩并苯。在下一步中，最有前途的PS-CAT二联体将被功能化，以使其能够掺入软物质基质中。

The project aims at the synthesis, characterization and application of noble metal-free, highly active visible light-driven molecular HER photocatalysts. Development of covalent PS-CAT dyads by covalently linking π-conjugated thienoacenes as visible light photosensitizers to iron hydrogenase-inspired diiron complexes as HER catalysts will be studied. Chemical modification at the iron coordination environment is used to optimize the catalytic activity. As alternative catalyst models, molecular molybdenum sulfides will be covalently linked to suitable thienoacenes. In a next step, the most promising PS-CAT dyads will be functionalized to enable incorporation into soft matter matrices.
