Perovskite quantum dots are promising classical and quantum light emitters but have limited chemical and colloidal stability in polar solvents due to their highly ionic lattices. In this work we demonstrate that perovskite quantum dots capped with strongly binding Gemini ligands with thin 0.7 nm hydroxyl-terminated ligands can be colloidally dispersed in polar solvents like ethanol.
