we study a novel strategy to develop polymer field effect transistors using ethanol, propanol, and butanol as processing solvents. From such environmentally benign processes, for the first time we demonstrate high-mobility (>1 cm2/Vs) polymer field effect transistors. These mobility values realized from ‘really green solvents’ exceed those of conventional hydrogenated amorphous silicon semiconductors. To achieve this, we fabricate stable sub-microparticles of conjugated polymers dispersed in alcohols, develop an aldehyde-assisted surface tension-depression methodology to successfully form thin films from alcohol, and carefully characterize the structural information of alcohol-dispersed sub-microparticles of semiconducting polymers. |
