Abstract Semiconducting nanocrystals have attracted world‐wide research interest in artificial photosynthesis due to their appealing properties and enticing potentials converting solar energy into valuable chemicals. Compared 0D nanoparticles, 1D nanorods afford long‐distance charge carriers separation extended lifetime the release of quantum confinement axial direction. Herein, stable CsPbBr 3 distinctive dimensions are crafted without altering morphology via grafting hydrophobic polystyrene (PS) chains through a post‐synthesis ligand exchange process. The resulting PS‐capped exhibit series enhanced stabilities against UV irradiation, elevated temperature, polar solvent, making them promising candidates for photo‐induced atom transfer radical polymerization (ATRP). Tailoring surface chemistry dimension endows stable, but variable reaction kinetics ATRP methyl methacrylate. trapping‐detrapping process photogenerated lead lengthened nanorods, contributing facilitated ATRP. Therefore, by leveraging such effects dynamics on its photocatalytic performance scrutinized, providing fundamental understandings designing next‐generation efficient nanostructured photocatalyst conversion.
