Novel organic ligands, chelate complexes, and multi-electron storage photocharge separation molecular devices

摘要

To provide a novel organic ligand, a chelate complex, and a multi-electron storage type photocharge separation photomolecular device for artificial photosynthesis. The novel organic ligand of the present invention is represented by the general formula [I]: R1-Z-R2 (wherein R1, Z and R2 all have the same meaning as described above). The chelate complex of the present invention can be produced by reacting the above-mentioned organic ligand with a metal atom ion such as Ru (II) ion, and the obtained chelate complex has various anions such as PF6-ion. Function as a photomolecular device that can reproduce the behavior very similar to the cooperative behavior of photochemical reaction system I (PSI) and NADP + reductase, which is equivalent to a part of photosynthesis performed by plants. Can do. Furthermore, the photomolecular device of the present invention also functions as a photochemical hydrogen energy production device capable of producing hydrogen energy photochemically by combining with a platinum complex catalyst that generates hydrogen gas in one step of two electrons. Can do.
