The experimental procedure for recyclability of PCPF-1 shown in the Electronic Supplementary Information (ESI) should be replaced with the following optimized procedure.

“The recyclability of PCPF-1 was examined in the context of adsorbing liquid-phase n-hexane. For the recycle experiment, 53.5mg PCPF-1 was put in a filter with inner joint, liquid hexane was then added and weighted before hexane starts to filter out. The weighted mixture sample was vacuumed on a filter bottle for 10 min, and new portions of liquid hexane were then added to the filter for the next cycle, which was performed under otherwise identical conditions.”

Fig. S10 in the ESI should also be replaced with the following figure, which better reflects the recyclability of PCPF-1.

The data for the recyclability experiment is listed in the following table, which should have been included as Table S1 in the ESI.
