Innovative approaches to the molecular design, synthesis, and functionalization of conjugated organic polymer (D–A, D–π–A, A–A–D, and A–D–A) photocatalysts for sustainable hydrogen production

The exploration of conjugated polymers with various donor–acceptor types (D–A, D–π–A, D–A–A, and D–π–A–A) for developments in side-chain substitution, conjugation expansion, and the creation of photocatalysts for hydrogen generation is reviewed.
