Outline of Final Research Achievements

Polycyclic aromatic hydrocarbons (PAHs) fused by six-membered silicon-containing rings and V-shaped cyclic dimers of silylanthracenes were obtained by reaction through C-H cleavage of silylated PAHs under the presence of a ruthenium catalyst and unsaturated hydrocarbons. The structures of the obtained compounds were determined by single-crystal X-ray analysis. The behavior of light absorption and emission was investigated by spectroscopic analysis and density functional theory calculation. Bathochromic shifts of absorption and emission was observed by fusing the six-membered silicon-containing rings. V-shaped cyclic dimers of silylanthracenes showed the behavior probably derived from intra- and intermolecular interaction of the anthracene moieties.
