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.

稠合芳族化合物的化学形成需要多种步骤和努力。我们发现了一种在溶液中用紫外光辐射合成纯稠环芳烃化合物的新方法。用这种方法，我们制备了稠环芳烃化合物和含氧、氮、硫原子的五元芳烃化合物。这些化合物的光物理和光化学性质已被揭示，利用它们作为有效的发光材料。为了将它们应用于电子材料如场效应晶体管（FET）中的电子传输层，测量了电子迁移率。利用激光闪光光解技术研究了光凝聚法的光化学机理。
