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。本文将研究以π偶联的噻吩类化合物为可见光光敏剂，以铁氢酶激发的二铁络合物为催化剂，合成共价PS-CAT二元体。采用铁配位环境下的化学修饰来优化催化剂的活性。作为替代催化剂模型，硫化钼分子将与合适的亚硫烯共价连接。在下一步，最有希望的PS-CAT二元组分将被功能化，以使其能够并入软物质矩阵。

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.
