A tri-stable structural switching between different polymorphisms is presented in the 2D mol. assembly of a 5-(benzyloxy)isophthalic acid derivative (BIC-C12) at the liquid/solid interface. The assembled structure of BIC-C12 is sensitive to the applied voltage between the STM tip and the sample surface. A compact lamellar structure is exclusively observed at pos. sample bias, while a porous honeycomb structure or a quadrangular structure is preferred at neg. sample bias. Selective switching between the lamellar structure and the honeycomb structure or the quadrangular structure is realized by controlling the polarity and magnitude of the sample bias. The transition between the honeycomb structure and the quadrangular structure is, however, absent in the assembly. This tri-stable structural switching is closely related to the mol. concentration in the liquid phase. This result provides insights into the effect of external elec. field on mol. assembly and benefits the design and construction of switchable mol. architectures on surfaces.
