Investigating the Role π‑Rich Solvents Play in the Growth of Cesium Lead Bromide Nanocrystals.

ABSTRACT: In this report, the role that a high-boiling-point solvent type plays on the nucleation and growth, morphology, and crystal-phase transformation of cesium lead bromide nanocrystals (CsPbBr₃) is studied. The CsPbBr₃ products were compared between a one-pot growth mechanism at room temperature (RT) versus a hot-injection mechanism (HI) control using dibenzyl ether (DBE), diphenyl ether (DPE), dioctyl ether (DOE), or 1-octadecene (ODE). The coordination between these solvents and the PbBr₂ salt precursors resulted in different plumbate [PbSBr _n ]^2-n precursors being formed. The S-to-Pb²⁺ coordination within [PbSBr _n ]^2-n was probed by UV-vis and solvent-phase ²⁰⁷Pb NM
