Outline of Final Research Achievements

We have demonstrated that nano- micro-structured coordination polymers can be used as precursors for inorganic nano- and microstructures.
We synthesized chiroptical Ag2S-based nanohelices derived from helical coordination polymers (CPs). Right- and left-handed coordination helices used as precursors were prepared from l- and d-glutathione with Ag+ and Cu2+. Pyrolysis of the coordination helices gave right- and left-handed helices of Cu0.12Ag1.94S/C, which exhibit chiroptical activity spanning the entire visible light region.
In the second project, we have demonstrated that CPs can be used as precursors for photocatalysts without stabilizers. The pyrolysis of CP nanowires of [Cd(l‐cysteinate)]n gave CdS/C nanowires that exhibit photocatalytic activity for hydrogen generation superior to CdS nanowires with organic stabilizers.
