Chemical formation of fused aromatic compounds requires a variety of steps and efforts. We have found a new method for synthesizing pure condensed aromatic compounds by UV light irradiation in solution. With this method, we have prepared polyaromatic fuzed compounds and five-membered aromatic compounds containing oxygen, nitrogen and sulfur atoms. Photophysical and photochemical properties of these compounds have been revealed for utilizing them as efficient luminescent materials. For the aim of applying them to electronic materials such as an electron transfer layer in field-effect transistors (FET), the electron mobility was measured. The photochemical mechanism of the photocondensation method was investigated by using laser flash photolysis techniques.
