A series of novel donor–acceptor (D–A) type viologens with through‐space conjugation (TSC) are synthesized. The synergistic effect of D–A conjugation and TSC endow these compounds with a narrower energy gap, excellent redox properties, strong absorption in the visible range (up to 450 nm), and high efficiency of intramolecular charge transfer (ICT). These compounds also exhibit a long‐lived charge separation state and stable radical formation. Considering their impressive photophysical and redox properties, TSC viologens with D–A conjugation are explored for visible‐light‐driven photocatalysis. As a catalyst in oxidative coupling reactions under visible light, compound 9 can achieve a yield of 94%, attributed to its strong ICT effect. Additionally, hybridized into graphitic carbon nitride (g‐C₃N₄), compound 9 enhances hydrogen production performance under visible light, achieving an H2 generation rate of 4102 µmol h−1g−1. This study highlights the potential applications of TSC viologens in photocatalytic systems.

Graphitic carbon nitride (g‐C3N4) is a prominent photocatalyst that has attracted substantial interest in the field of photocatalytic environmental remediation due to the low cost of fabrication, robust chemical structure, adaptable and tunable energy bandgaps, superior photoelectrochemical properties, cost‐effective feedstocks, and distinctive framework. Nonetheless, the practical application of bulk g‐C3N4 in the photocatalysis field is limited by the fast recombination of photogenerated e−‐h+ pairs, insufficient surface‐active sites, and restricted redox capacity. Consequently, a great deal of research has been devoted to solving these scientific challenges for large‐scale applications. This review concisely presents the latest advancements in g‐C3N4‐based photocatalyst modification strategies, and offers a comprehensive analysis of the benefits and preparation techniques for each strategy. It aims to articulate the complex relationship between theory, microstructure, and activities of g‐C3N4‐based photocatalysts for atmospheric protection. Finally, both the challenges and opportunities for the development of g‐C3N4‐based photocatalysts are highlighted. It is highly believed that this special review will provide new insight into the synthesis, modification, and broadening of g‐C3N4‐based photocatalysts for atmospheric protection.
