a Schematic of the COFTP-Py synthesis. b Crystal size and growth rate in this work (sc-COFs and os-COFs) compared with some best-reported results. The red star indicates the best result in sc-CO2. c, d SEM images of sc-COFTP-Py (5 min) and os-COFTP-Py (3 days). e PXRD patterns of sc-COFs (5 or 90 min), os-COFs (3 days), os-COFs (30 or 90 min), and the simulated patterns. The characteristic peaks are marked by stars. The scale bars are 10 μm.
