| Outline of Final Research Achievements |
Organic conjugated compounds based on nitrogen-containing heterocycles have good electron-donating and accepting properties. We synthesized novel nitrogen-containing heterocyclic compounds based on imide, carbazole and diazaborole units, and investigated their molecular structures, redox and optical properties, and carrier transporting properties. Introduction of a trifluoromethylphenyl group improved their photoluminescence (PL) efficiency and some of them afforded good intramolecular charge transfer emission. The trifluoromethylphenyl groups also played an important role to decide molecular arrangements in the solids. Compounds forming noncentrosymmetric arrangements showed clear triboluminescence (TL). Introduction of further conjugated units and preparation of mixed solids improved solid PL and TL properties. New benzothiadiazole derivatives were prepared and applied to n-type semiconductors for field-effect transistors (FETs) and organic solar cells.
