Nanoscopically engineered organic semiconducting materials have attracted great interest recently as they are promising building blocks for various electronic and optoelectronic applications. In addition, multicomponent semiconducting materials such as p-n junctions or core-shell structures are of great importance both in modern electronic applications and in understanding other semiconductor devices. They can potentially realize novel or improved chemical and physical properties that cannot be obtained from the single component system or their bulk materials. In this study, unconventional organic semiconducting nanomaterials including branched nanowires, nanoporous organic semiconducting films, and core-shell structured 1-D nanomaterials have been fabricated, and applied in high-performance flexible and wearable sensors such as photodetectors, chemical and biological sensors. In addition, we demonstrate a highly effective multiple pattern of metal electrodes as back reflectors to fabricate solution-processable organic photovoltaics, organic photodiodes and organic phototransistors, by employing block-copolymer lithography and nano-imprinting lithography. |
