Chiral Perovskite Nanocrystals Templated by Achiral Block Copolymer Micelles with High Chiroptical Property and Stability |
| 초록 |
Chiral perovskites have emerged as promising candidates for potential chiroptical devices. However, preparing chiral perovskites with CPL emission at room temperature (RT) and high stability still remains a challenge. Here, we present a novel route for fabricating chiral perovskite nanocrystals (NCs) templated by block copolymer (BCP) inverse micelles consisting of achiral BCP and racemic mixture, DL-alanine. Due to coordination interaction, chirality transfer effectively occurs from chiral micellar cores to perovskite NCs. Besides, the fabricated perovskite NCs emit CPL at RT. Since the hydrophobic PS shell protects perovskite NCs and the amine group of DL-ala strongly interacts with perovskite NCs, stability will be remarkably enhanced. This proposed strategy offers a promising way to prepare chiral perovskites based on supramolecular systems, allowing the large-scale synthesis and solution processibility. |
