Designer Phospholipid Capping Ligands for Soft Metal Halide Nanocrystals
(2023)Research SquareThe success of colloidal semiconductor nanocrystals (NCs) in science and optoelectronics is inextricable from their surfaces. The functionalization of lead halide perovskite (LHP) NCs poses a formidable challenge due to their structural lability, unlike the well-established covalent ligandcapping of conventional semiconductor NCs. We posited that the vast and facile molecular engineering of phospholipids as zwitterionic surfactants can ...Working Paper -
Colloidal aziridinium lead bromide quantum dots
(2023)Research SquareThe compositional engineering of lead-halide perovskite nanocrystals (NCs) via the A-site cation represents a lever to fine-tune their structural and electronic properties. However, the presently available chemical space remains minimal since, thus far, only three A-site cations have been reported to favor the formation of stable lead-halide perovskite NCs, i.e., Cs⁺ , formamidinium (FA), and methylammonium (MA). Inspired by recent reports ...Working Paper
