Outline of Final Research Achievements

The unique redox-switching system of orthoquinone-containing pentacyclic aromatic compounds using molecular hydrogen and oxygen in the presence of a heterogeneous Pd nano particle catalyst (SAPd) was discovered. These molecules were predicted by in silico screening before synthesis. Efficient synthetic protocols for orthoquinone-containing aromatic compounds via Pd-mediated homocoupling and the benzoin condensation reaction were developed. The obvious switching phenomena in photoluminescence property between orthoquinone and hydroquinone aromatic compounds were observed. In addition, the twist strain of the orthoquinone moiety could induce dramatic changes in color and emission. In addition, these polyaromatic compounds were applied to the ligand of magnetic metal complex.
