Outline of Final Research Achievements

This project of final goal is development of novel solution-processed organic semiconductor devices that can be converted from alcohol soluble organic precursor. To develop this purpose, novel organic materials and a series of substituent group were investigated in this project. 5,5'-Alkylsubsituted leucoindigo could soluble to alcohol such as ethanol with high solubility, and it could convert to corresponding indigo by oxygen as chemical oxidant. This leuco structure material could allow to fabricate for thin-film structure device by solution-process, also converted to indigo by oxygen. The film device showed opt-electronic response and showed current, suggested this system can be used for oxygen chemical sensor under opt-electronic measurement condition.
