Fig. 6 — SV plots of d-Zn-HOIF NFs triggered by adding (a) (1R,2R)- and (1S,2S)-DACH, (b) (R)- and (S)−2-butanol, (c) d- and l-lactic acid. Blank curves present the tests free of analytes. Error bars represent standard deviations of three independent replicates. d Enantioselective quenching ratio (QR) of tested chiral aliphatic compounds with various steric hindrances. The red asterisks represent the chiral centers. e Self-purified and recyclable d-Zn-HOIF NFs for enantioselective recognition of (1R,2R)- and (1S,2S)-DACH during three consecutive cycles. I_o stands for the initial FL intensity, while I_R and I_s represent the FL intensity after testing R- and S-enantiomer, respectively. f PXRD plots of reassembled d-Zn-HOIF NFs in comparison to the raw sample after each cycle.
