Development of planographic printing method utilizing photochromic reactions and its application in organic electronics

近年来，有机材料已应用于有机电致发光、有机薄膜太阳能电池和有机薄膜晶体管器件。这些有机电子器件具有重量轻和柔性的特性。此外，期望它们可以通过使用印刷技术而不是使用诸如气相沉积的真空处理来以低成本制造。然而，为了实现上述装置，需要研究开发新材料和新印刷工艺。在本研究项目中，实施了基础研究，以开发利用光致变色反应的平版印刷方法及其在有机电子学中的应用。

Recently, organic materials have been applied in organic electroluminescence, organic thin film solar cell, and organic thin film transistor devices. These organic electronic devices have characteristics in their light weight and flexible. In addition, it is expected that they can be fabricated in low cost by using printing technologies instead of using vacuum processing such as vapor depositions. However, research in developing new materials and new printing processes is required for the realization of above-mentioned devices. In this research project, basic investigations was implemented for the development of planographic printing method utilizing photochromic reactions and its application in organic electronics.
