Figure 1. Schematic diagram of the post-modification process. (A) The new post-modified method for PAF-1; (B) 13C CP/MAS NMR spectrum of PAF-1 and PAF-1-Cl; (C and D) XPS C 1s and Cl 2p spectrum of PAF-1 and PAF-1-Cl. PAF-1: Porous aromatic framework-1; CP/MAS: cross-polarization/magic angle spinning; NMR: nuclear magnetic resonance; XPS: X-ray photoelectron spectroscopy.
