Abstract

Organic Nanoparticles for Photocatalytic Hydrogen Evaluation In the Research Article (DOI: 10.1002/adom.202500678), Sae Byeok Jo and co-workers reveal the photophysical governance of “dark” excited states in organic heterojunction nanoparticles in water, enabling highly efficient broadband photocatalytic hydrogen evolutions. By inducing new transition routes that extend charge generation timescale, chronic limitations from the predominance of short-lived singlets are alleviated.
