| Research Abstract |
The research project aims at elucidating the multi-electron transfer process of oxygen molecules incorporated into the macromolecule-metal complexes, in order to establish novel molecular conversion processes which are promoted by the four-electron reduction of oxygen.
Followings have been established : Detailed analysis of the oxygen splitting reaction by one-step four-electron transfer, establishment of oxidative polymerization facilitated by multi-electron transfer process, elucidation of multi-electron transfer process in molecular assemblies. Based on these results, a general strategy to allow molecular conversions to proceed efficiently by multi-electron transfer process has been provided.
1. Multi-nuclear metal complexes that show one-step multi-electron transfer processes were synthesized and their structure was determined. A general method to provide a one-step multi-electron transfer was provided.
2. Oxygen splitting reaction by way of a μ-dioxo intermediate MOM-OO-MOM was established.
3. Synthesis of novel compounds, polysulfoniums and polythioethers, were established, and their properties were determined in detail.
4. Structure and properties of molecular assembly systems were elucidated, in terms of photoelectron transfer process.
5. Synthesis of high molecular-weight polyheteroacenes were established, and their physicochemical properties were determined.
