Supermolecule-assisted synthesis of perovskite nanorods with high PLQY for standard blue emission

A supermolecule-assisted approach is reported to afford perovskite nanorods (NRs) with a standard blue emission of 462 nm and a colloidal PLQY of ∼90%. The PL intensity of the NRs is almost unchanged for one week and remains 60% after 40 days.
