{"doi":"10.1002/cphc.202500061","title":"Origin of Intrinsic Chirality in Cysteine‐Passivated Metal Halide Perovskite Nanoclusters","abstract":"Ligand-assisted perovskite nanoclusters (PNCs) have been synthesized using oleylamine and L- or D-cysteine as confirmed based on their characteristic electronic absorption bands around 430 nm based on ultraviolet-visible spectra. Circular dichroism (CD) spectra show distinct chiroptical bands in the 430-440 nm region, revealing the chirality of the PNCs. Interestingly, the sign of the CD signal is always negative, independent of the chirality for L- or D-cystine. This 430-440 nm CD band is tentatively attributed to the formation of new chiral stereocenters within the PNCs with an uneven ratio of two enantiomers induced by the asymmetric liquid-liquid interface from the solvent and antisolvent used during synthesis.","journal":"ChemPhysChem","year":2025,"id":533568,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":2,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9534,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1415360,"name":"David C.
