Thiocarboxylic acids for robust passivation and advanced applications of perovskite nanocrystals

Abstract

Thiocarboxylic acid ligands provide strong surface passivation, improving the thermal, water, and long-term stability of the PeNCs. An adamantane framework was adopted as a designable alkyl tail to improve the thin-film morphology owing to strong intermolecular interactions. Furthermore, light-emitting diodes were fabricated to demonstrate the broad applicability of the thiocarboxylic acid ligands.
