Multidentate Molecule Anchoring Halide Perovskite Surface and Regulating Crystallization Kinetics toward Efficient Light‐Emitting Diodes (Small 11/2023)

Abstract

Efficient Light-Emitting Diodes In article number 2205336, Yue-Min Xie, You-Yong Li, Man-Keung Fung, and co-workers introduce a novel multidentate molecule (Formamidine Sulfinic Acid, FSA) to heal perovskite defects, where the intense bonding strength of the S≐O and –NH2 groups of the multidentate molecule to the undercoordinated Pb defects can effectively facilitate the passivation of the perovskites, thus leading to modified perovskite crystallization properties with enhanced passivation durability.
