제목 Organic phototransistors with bulk heterojunction sensing layers containing difluorinated diketopyrrolopyrrole
초록 Diketopyrrolopyrrole (DPP) dyes have been widely used for various applications including inks and paints due to their outstanding stability. Their particular optical absorption and crystalline characteristics motivated further development of semiconducting DPP derivatives for organic electronic devices such as organic field-effect transistors (OFETs), organic solar cells (OSCs), organic photodetectors (OPDs), etc. Recently, our group tried to synthesize series of DPP derivatives containing difluorinated functional groups and applied them as an electron acceptor in the bulk heterojunction (BHJ)-type sensing channel layers of organic phototransistors. In this presentation, we discuss the synthesis of the difluorinated DPP derivatives and demonstrate their roles in organic phototransistors with the BHJ sensing channel layers.
