Correction: Mechanism unravelling for ultrafast and selective ⁹⁹TcO₄^– uptake by a radiation-resistant cationic covalent organic framework: a combined radiological experiment and molecular dynamics simulation study

Abstract

Correction for ‘Mechanism unravelling for ultrafast and selective ⁹⁹TcO₄^– uptake by a radiation-resistant cationic covalent organic framework: a combined radiological experiment and molecular dynamics simulation study’ by Linwei He et al., Chem. Sci., 2019, DOI: ; 10.1039/c9sc00172g.

An error occurred when we plotted some of the figures in this paper, caused by totally unintentional misoperation. When plotting Fig. 2d, e and S5, the misoperation of batch input of the XRD data leads to the repeating patterns in the above mentioned figures. We have rechecked our raw data carefully and would like to make a correction to Fig. 2d and e using the updated figures generated by the raw data shown below. An updated ESI file containing the correct version of Fig. S5 is also provided.

Fig. 1. (a) N₂ sorption isotherms of SCU-COF-1 after different treatments with 3 M HNO₃, 600 kGy β-rays, and 600 kGy γ-rays at 77 K. (b) Pore-size distribution of SCU-COF-1 calculated by NLDFT modelling based on N₂ adsorption data. (c) IR spectra of SCU-COF-1 and SCU-COF-1 after treatment with 3 M HNO₃, 600 kGy γ-irradiation, 600 kGy β-irradiation, and stock solution containing ReO₄^–. (d) PXRD patterns of SCU-COF-1 after treatments in various solvents and acids for 48 h. (e) PXRD patterns of SCU-COF-1 after being irradiated with various doses of β-irradiation (50 kGy, 200 kGy, 400 kGy, 600 kGy). (f) ¹³C solid NMR spectrum of SCU-COF-1.
