New type of organic semiconductors such as (1) chalcogene containing π-conjugated compounds and (2) δ-π conjugated compounds were synthesized and applied for the organic devices (organic transistors, organic EL, etc.). For example, organic field-effect transistors (OFETs) using chalcogene-containing semiconductors as active layers have been successfully fabricated. I have found that a series of dichalcogenophenones perform as good p-type transistors. In particular, diphenyl-benzodiselenophene demonstrates a remarkably high FET performance with field-effect mobility of 0.17 cm^2/Vs and on/off current ratio of 10^5. Further investigation is underway for the similar fused selenophene compounds. I have proposed new PL imaging method using δ-π conjugated compounds. This is quite unique and simple process for the organic EL devices.

新型有机半导体如（1）含硫属元素的π-共轭化合物和（2）δ-π共轭化合物的合成和应用于有机器件（有机晶体管、有机EL等）。例如，已经成功地制造了使用含硫族元素的半导体作为有源层的有机场效应晶体管（OFFET）。我发现一系列的二硫代苯甲酮可以作为良好的p型晶体管。特别是，二苯基苯并二硒醚表现出非常高的FET性能，场效应迁移率为0.17 cm^2/Vs，开/关电流比为10^5。对类似的稠合硒化合物的进一步研究正在进行中。提出了一种新的δ-π共轭化合物光致发光成像方法。这对于有机EL器件来说是非常独特和简单的工艺。
