Abstract
We numerically show that molecules adsorbed in a soft porous crystal form a superlattice (SL) stabilized by elastic interactions. In a mechanically flexible honeycomb lattice model, when the elastic interactions between the next nearest neighboring lattice sites are strong, a long-range ordered 1/3-filling SL state emerges. By calculating the thermodynamic stability, it is found that the SL state is robust against thermal fluctuation. Our results provide a mechanism of elasticity-driven SL formation, which can be utilized for controlling the distribution of adsorbed molecules.
