| 논문초록 | Conventional Organic photocatalysts exhibit inefficient photocatalytic activities due to high exciton binding energy, short exciton diffusion lengths (EDL), and poor ambipolar charge mobility. The nanoparticles (NPs) with internal heterojunctions have attracted great attention recently due to their ability to separate the charges efficiently. However, maintaining homogeneity in size and composition with long-term stability at a commercial scale is quite challenging with these NPs. Here, we introduce a novel strategy of using “dark excitonic” organic NPs that are capable of bypassing the conventional exciton dissociation pathways. Further, the poor mobility issue is tackled by introducing low-level doping of the second component. Additionally, the short EDL is found to be derived from a high polaron yield, promoting efficient generation. Hence, high charge generation is possible with a single component removing difficulty in maintaining homogeneity in composition and morphology. |
