Semiconductor　quantum　dots　(QDs),　as　a　newfashioned　light-absorbing　material　with　great　promise　in　artificial　photosystems,　generally　exhibit　attractive　photoactivity　and　selectivity　in　organic　photoredox　transformation　thanks　to　their　tunable　redox　potential,　high-efficiency　light　harvesting　capability,　and　high　extinction　coefficient　in　the　visible　region.　Utilizing　QDs　as　a　versatile　platform　to　convert　organic　compounds　into　value-added　feedstocks　provides　an　effective　way　to　alleviate　energy　and　chemical　feedstock　supply　problems.　In　this　review,　we　concisely　summarize　the　basic　principles　of　photocatalytic　organic　conversions　over　semiconductor　QDs　and　the　effects　of　grain　size,　surface　active　sites　and　ligands　on　their　catalytic　performance.　Then,　we　highlight　the　recent　progress　of　QDs　enabling　multifarious　photocatalytic　organic　transformations,　including　nitroaromatic　reduction,　selective　alcohol　oxidation,　sulfide　oxidation,　C-H　functionalization　and　so　on.　In　the　end,　we　discuss　the　current　challenges　and　future　prospects　in　further　developing　efficient　semiconductor　QD-based　photocatalysts　toward　photoredox-catalyzed　organic　conversion.　©　2023　The　Royal　Society　of　Chemistry.
