Exploring Pb‐Chelation Chemistry in the Crystallization Dynamics of Halide Perovskites
Advanced Functional Materials, EarlyView.A mechanism of how Pb‐chelation chemistry governs coordination geometry and initial nucleation behavior at the precursor level of halide perovskite, by regulating the deprotonation state of a chelating additive, is elucidated. This allows for innovative reaction‐system design principles that promote coherent growth while suppressing defect formation in
