Chiral optoelectronic has gathered significant attention in a variety applications of quantum computation, bio-sensing, 3D imaging and encryption. Above all, development of chiroptical semiconducting materials, which can distinguish the handedness of circularly polarized (CP) light polarization is prerequisite to realize such chiroptoelectronic devices. Recently, diketopyrrolopyrrole (DPP)-based conjugated molecules have received special attention as the most promising organic semiconductor with excellent light absorption and charge transport properties. However, chiroptical DPP-based molecules are rarely reported. In this work, we propose chiroptical DPP-based organogelator. Functionalized chiral amino acid inducing the strong intermolecular interaction was incorporated to the DPP-conjugated core, which resulted in the self-assembled supramolecular structure with chiroptical activity. Synthesis, chiroptical properties and nanostructure of DPP-based organogelator will be presented.
