Interplay between Perovskite Magic-Sized Clusters and Amino Lead Halide Molecular Clusters.

ABSTRACT: Recent progress has been made on the synthesis and characterization of metal halide perovskite magic-sized clusters (PMSCs) with ABX ₃ composition (A = CH₃NH₃ ⁺ or Cs⁺, B = Pb²⁺, and X = Cl^-, Br^-, or I^-). However, their mechanism of growth and structure is still not well understood. In our effort to understand their structure and growth, we discovered that a new species can be formed without the CH₃NH₃ ⁺ component, which we name as molecular clusters (MCs). Specifically, CH₃NH₃PbBr₃ PMSCs, with a characteristic absorption peak at 424 nm, are synthesized using PbBr₂ and CH₃NH
