To further investigate this delamination into MONs, ultrasound assisted liquid phase exfoliation of bulk GUF-14 (hxl) was performed at 37 kHz for 12 h in a range of different solvents (SI, Section S7). The nanosheets were then isolated from suspensions by centrifugation at 1500 rpm for 1 h to remove unexfoliated MOF and larger fragments.
