Fig. 2

a Schematic of the reduction of COF-300 to yield COF-300-AR. Time-lapsed DFM images of (b) single COF-300 and c COF-300-AR individual in the presence of chloroform vapour (0.84 bar, 25 °C). Scale bars are 4 μm. d The corresponding roundness change (ΔR) of single COF-300 and COF-300-AR as a function of reaction time. e Particle-averaged ΔR of COF-300 and COF-300-AR crystals under different reaction time. Error bars stand for the standard deviations of ΔR.
