Author Correction: Non-solvent post-modifications with volatile reagents for remarkably porous ketone functionalized polymers of intrinsic microporosity (Nature Communications, (2023), 14, 1, (2096), 10.1038/s41467-023-37743-y)

Abstract

The original version of this Article contained an error in Fig. 2 and supplementary Figures 1, 2, 3 and 48, in which the structure of PIM-1 is displayed wrongly. The correct version of Fig. 2 and Supplementary Figures 1, 2, 3 and 48 are: Fig. 2: The quantitative post-modification of PIM-1 through conventional and non-solvent methods with a volatile Grignard reagent, methylmagnesium bromide (CH3MgBr). Ketone-PIM−1 (K-PIM-1) was further reacted by the same reagent to make Alcohol-PIM−1 (OH-PIM-1) with remarkably high retention of porosity, considering the two-step reaction. Solvent: (i) CH3MgBr in tetrahydrofuran (THF), THF solvent at 0 °C → RT for 24 h (ii) 0.5 M hydrochloric acid (HCl) in methanol (MeOH), H2O at 60 °C for 4 h. Non-solvent: (i) CH3MgBr in diethyl ether (Et2O) at 0 °C → RT for 24 h (ii) 0.5 M HCl in MeOH, H2O at 60 °C for 4 h. K-PIM−1 was further functionalized by phenylhydrazine (PhNHNH2) and polyethylenimine (PEI) to show versatility in the reactive portfolio and to create CO2 adsorbents. Supplementary Figure 1: Synthesis of PIM-1 via low temperature approach. Supplementary Figure 2: Synthesis of PIM-1 via high temperature approach. Supplementary Figure 3: Control reaction using PIM-1 as a starting material to react with phenylhydrazine (PhNHNH2) and polyethylenimine (PEI), refluxed in the presence of ethanol solvent (EtOH) under mild acidic condition. Supplementary Figure 48: a Mechanism and b FT-IR spectra revealed the reversible reaction of HZ-PIM-1. which replace the previous incorrect versions: Fig. 2:The quantitative post-modification of PIM-1 through conventional and non-solvent methods with a volatile Grignard reagent, methylmagnesium bromide (CH3MgBr).
