| Outline of Final Research Achievements |
To develop novel high refractive index polymers, we investigated the synthesis and polymerization of bismuth-containing monomers. For example, styrylebismuthine was obtained as a stable monomer. Its thermal homopolymerization proceeded efficiently without solvents under nitrogen. In addition, we prepared polymer films based on the polymerization, and evaluated the optical properties. As a result, the refractive index (nD) of the polymer film was 1.69.
