a, Honeycomb, square and kagome 2D PAVs synthesized from 2D PIs and C2-symmetric acetonitrile monomers. (i) Cs2CO3, 120–130 °C, DMAc/H2O, 6–8 days. b, Honeycomb 2D PAVs synthesized from 2D PIs and C3-symmetric acetonitrile monomers. (ii) Cs2CO3, 120–130 °C, DMAc/H2O, 6–12 days. The pictures within each of the structures are photos of the powder obtained.
