Abstract Over the past decades, excessive CO₂ emissions have caused severe environmental problems, primarily global warming and climate change. To address these challenges, researchers developed photocatalytic approaches to convert into high‐value‐added chemicals. The development of efficient, green, cost‐effective reduction systems represents a crucial step toward sustainable energy solutions. However, replacing noble metal‐based photosensitizers, which are widely used in reduction, with more alternatives remains challenging. Thermally activated delayed fluorescence (TADF) compounds emerged as promising organic offering high quantum efficiency, long lifetimes, wide redox window. Notably, 1,2,3,5‐Tetrakis(carbazol‐9‐yl)‐4,6‐dicyanobenzene (4CzIPN), prototypical TADF compound, has demonstrated exceptional performance various systems. This review systematically summarizes recent advances TADF‐based particularly 4CzIPN, for while elucidating their underlying reaction mechanisms.
