Fig. 1: Schematic diagram of the solvothermal temperature-regulated pore evolution of Zn2(datrz)2CO3 series.

Increasing solvothermal temperature induces gradual ligand rotation, widening the pores from Zn2(datrz)2CO3-180 to -220 and shifting molecular recognition from C3H6/C3H8 sieving to CO2 capture. (Color code: C, gray; N, blue; O, red; H, white).
