a Comparison of the FT-IR spectra of B[f]QCOF-1 and corresponding imine-based COF-1. b The solid state 13C cross polarization magic angle spinning (13C CP/MAS) NMR spectrum of B[f]QCOF-1. Asterisks in the spectrum indicate the ssNMR spinning sidebands. c High resolution N1s XPS spectra of B[f]QCOF-1 and corresponding COF-1. d The experimental, simulated and Pawley refined PXRD patterns for the eclipsed AA stacking mode of B[f]QCOF-1. e The proposed eclipsed structure of B[f]QCOF-1. f N2 adsorption and desorption isotherm of B[f]QCOF-1 measured at 77 K. (Inset: the pore size distribution of B[f]QCOF-1 derived from NLDFT).
