Chiral Lead Halide Perovskite Nanocrystals: Construction Strategies and Photophysical Properties

Abstract Lead halide perovskite nanocrystals (PeNCs) have attracted intense interest by virtue of their numerous remarkable optoelectronic properties, which render them promising for various optoelectronic applications. Over the past few years, substantial progress has been made in the study of chiral PeNCs, from the sample preparation, spectroscopic characterization to practical applications. In this review, the state‐of‐the‐art progress of the construction strategies and photophysical properties of chiral PeNCs has been summarized. The focus is placed on emerging developments in terms of synthetic methods, chiroptical properties, nonlinear optics, and chiral spintronics in chiral PeNCs. In the end, there is a discussion on the current challenges and future prospects in this versatile, rapidly evolving field.
