Outline of Final Research Achievements

Synthetic method for the regioselectively fluorinated polycyclic aromatic hydrocarbons (pinpoint-fluorinated PAHs) was developed. 1,1-Difluoroallenes and 1,1-difluoroalkenes were used as starting materials and the positions for the fluorine-introduction were perfectly controlled. The synthesized pinpoint-fluorinated PAHs were soluble in organic solvents and some pinpoint-fluorinated PAHs exhibited P-type semiconducting behavior. The pinpoint-fluorinated PAHs are a new category of organic semiconductors that can be used for printable organic electronic devices.
