Quinacridone-pyridine dicarboxylic acid based donor–acceptor supramolecular nanobelts for significantly enhanced photocatalytic hydrogen production

Self-assembled nanobelt photocatalysts with quinacridone containing different alkyl chains as donor and pyridine dicarboxylic acid as acceptor were firstly developed for H₂ evolution. SQAP-C4 without cocatalyst of Pt exhibited HER of 656 μmol h⁻¹ g⁻¹.
