(A) Schematic illustration of external electric field triggered network switching among the self-assembled molecular network, sCOFs-1 and sCOFs-2; (B)-(F) STM images showing the time-dependent conversion process from sCOFs-1 to sCOFs-2 with Vbias = −0.3 V (green and blue hexagons represents the porous structures of sCOFs-1 and sCOFs-2, respectively); (G) Plot of the coverages of sCOFs-1 and sCOFs-2 against time.
