Double-stage hexagonal COFs with fluorinated linkers.
(a,b) The schematic representations of (a) the synthesis of the HHTP-FFPBA-TATTA COF, HHTP-DFFPBA-TATTA COF and (b) the synthesis of the TATTA-FFPBA COF, TATTA-DFFPBA COF. (c–f) XRD patterns of (c) HHTP-FFPBA-TATTA COF, (d) HHTP-DFFPBA-TATTA COF, (e) TATTA-FFPBA COF and (f) TATTA-DFFPBA COF (red: experimentally observed, green: Pawley refinement, black: their difference, magenta: simulated with eclipsed AA stacking mode, purple: simulated with slipped AA stacking mode, blue: simulated with slipped AA-2 stacking mode, orange: simulated with staggered AB stacking mode).
