Figure 5. (A) Schematic showing the negligible Pb leakage and biocompatibility to living organisms of broken PSCs with supramolecular HPβCD-BTCA complex modification. and (B) schematic diagram of the lead capture mechanism of supramolecular HPβCD-BTCA complex. (C) Comparison of Pb sequestration for the damaged control and HPβCD-BTCA-modified PSCs. (D) Schematic illustration of Pb toxicity test procedures and (E) the corresponding results for the impacts of pristine perovskites and HPβCD-BTCA-chelated perovskites on the growth of E. coli. (F) Schematic illustration of Pb recycling and management in PSCs. Readapted with permission^[7]. Copyright © 2023 Springer Nature Limited.
