Solar-driven fast photocatalytic hydrogen evolution using size-minimized organic heterojunctions.

ABSTRACT: Pursuing small catalyst sizes has remained a constant endeavor to maximize reaction yields by exposing more active sites and/or enhancing charge extraction. Organic particle photocatalysts typically remain tens to hundreds of nanometers in size, constrained by the quasi-infinite conjugation of commonly used polymers. Here, we reveal the size-minimized organic heterojunction nanoparticles by using all small molecule photovoltaic materials, and significantly enhance their photocatalytic activities for solar-driven hydrogen evolution. Owing to the intrinsically weak intermolecular forces and the absence of molecular entanglement of small molecules, (sub)nanometer-scale diameters of polymer-free nanoparticles are yielded, representing a size reduction of 1-2 orders of magnitude than traditiona
