Berichtigung: Correction to “Modulating Skeletons of Covalent Organic Framework for High-Efficiency Gold Recovery”
1) The sentence on page 4, right column, line 20 of the main text has a typo. The statement “N+-PYTA-PATA-COF demonstrated that a new peak appeared at 67 ppm (Figure 2A, red curve)” should be replaced with “N+-PYTA-PATA-COF demonstrated that a new peak appeared at 57 ppm (Figure 2A, red curve)”.
2) In the main text (Page 4), the signal at 68 ppm should be assigned to residual solvent tetrahydrofuran (THF). Correspondingly, Figure 2A was revised by marking 68 ppm as THF signals. The corrected figure is shown below.
Figure 2 (A) The 13C NMR spectra of PYTA-PATA-COF (blue), PYTA-BDTA-COF (green), PYTA-TDTA-COF (purple) and N+-PYTA-PATA-COF (red), respectively.
3) In the Supporting Information, Figure S9, the PXRD curve for water-treated PYTA-BDTA-COF was inadvertedly repeated for NaOH-treated PYTA-BDTA-COF. The revised version of Figures S9 is presented below.
Figure S9. The PXRD patterns for PYTA-BDTA-COF under different conditions for one week.
4) In the Supporting Information, Figure S12, the PXRD curve for the NaOH-treated PYTA-PATA-COF and the NaOH-treated N+-PYTA-PATA-COF were incorrect. The revised versions of Figures S12A and S12D are presented below.
Figure S12. The PXRD patterns of (A) PYTA-PATA-COF and (D) N+-PYTA-PATA-COF after the treatment of DMF (black), DMSO (purple), CHCl3 (green), 6 M HCl (brown) and 6 M NaOH (cyan) for one week.
The original Supporting Information was replaced with the corrected version. The conclusions of this Research Article are not affected by these errors. The authors sincerely apologize for any inconvenience caused.
