The 𝑇 𝑟𝑖 4 𝐷𝑖 6 pore topology has point group T 𝑑 , with the total number of isomers arise from functionalization is 172. The FG pair distance histogram fingerprint of the pore using bdc and pbdc linkers in Figure . Expanding the linker to pbdc, would enlarge the 𝑇 𝑟𝑖 4 𝐷𝑖 6 pore, from d = 6.8 Å to 11.8Å.
