Perovskite nanocrystals (PeNCs) exhibit outstanding optical properties; however, surface and structural imperfections remain challenges. In this study, we designed new surface-passivating ligands aimed at addressing these issues. We systematically how each structural component of the ligands influences the PeNCs in terms of crystal structure and electronic states. Furthermore, LED devices incorporating these PeNCs were fabricated and evaluated, demonstrating functionality of the ligands and validating the proposed ligand design strategy.
