Metal complexes, which are composite inorganic/organic compounds, can be expected to exhibit unique physical properties due to their distinct structure and electronic states. We synthesize new metal complexes having a polymer structure, and after clarifying their structure, electronic states, and electrical conductivity, apply them in organic photoelectronic devices such as solar cells.
