Side Chain Elimination Enables Low‐Cost Fused‐Ring Acceptors and Reveals a Compact Tetrameric Structure for High‐Photocurrent Organic Solar Cells

Advanced Science, EarlyView.
β‐side chain elimination enables cost‐effective fused‐ring acceptors, JSM5 and JSM6, with simplified synthesis. The observed compact tetrameric structures induced by S···N intermolecular interactions lead to 3D charge transport and enhance intermolecular connectivity, delivering high short‐circuit current density up to 28 mA cm−2, a step closer to the ...

Furfuryl Alcohol‐Driven Proton Supply Enables Efficient Photocatalytic H2O2 Production Beyond Water‐Based Systems

Advanced Science, EarlyView.
A ZnIn2S4–carbon dot heterojunction enables photocatalytic H2O2 production coupled with furfuryl alcohol oxidation. In this redox system, furfuryl alcohol acts as both the electron donor and oxidation substrate, producing furoic acid with 100% selectivity and 98% conversion while supporting efficient H2O2 generation with a solar‐to‐chemical conversion (
