Novelπ-conjugated hetero-and carbocyclic compounds have been developed based on new synthetic methodology of "modular synthesis", aiming at improvement in efficiency of organic electronic devices as well as proof of principle of innovative concepts of devices. Noteworthy is that the versatility of fused furans has been found out to serve as stable and high-performance semiconducting materials. For example, an ambipolar benzodifuran allowed us to fabricate efficient homojunction OLED that emit light across the full visible color range and perform at a level close to the theoretical limit. A naphtodiduran showed even higher mobility than amorphous silicon. Novel stable n-type materials, such as benzophospholes and bis(cinnoline) s have been also developed, and their versatility has been demonstrated by applying them to cathode buffer materials in thin-film solar cells. Multifunctional materials, such as highly emissive ambipolar material, near infrared-light absorbing/emitting materials, have been successfully obtained as well.

基于“模块化合成”的新合成方法，开发了新型π共轭杂环和碳环化合物，旨在提高有机电子器件的效率以及器件创新概念的原理证明。值得注意的是，已发现稠合呋喃的多功能性可用作稳定和高性能的半导体材料。例如，双极性苯并二呋喃使我们能够制造出高效的同质结OLED，其在整个可见光颜色范围内发光，并在接近理论极限的水平下工作。萘二氢呋喃表现出比非晶硅更高的迁移率。新的稳定的n型材料，如苯并磷杂环戊二烯和双（噌啉）也已开发出来，它们的多功能性已通过将它们应用于薄膜太阳能电池的阴极缓冲材料而得到证明。多功能材料，如高发射双极性材料，近红外光吸收/发射材料，也已成功地获得。
