trolled linker apportionment in iZIF-8-LX-R%, we inspected
the possible models of linker apportionment to study the dis-
tances and distributions of ZIF frameworks. We found that
spatial distributions of pre-locked linker templates (LX) could
be influenced by the distance and orientation of imidazole lig-
ands in original frameworks. The ZIF cage was modelled as a
truncated octahedron, with the zinc nodes represented by the
vertices and the ligands represented by the edges of the poly-
hedron (Figure 4a). Faces of the polyhedron are comprised of
squares and hexagons. For conciseness, the spatial relation-
ship between ligands can be displayed through a projection on
the polyhedron. The orientations of two imidazole ligands can
be described as one of four different patterns: opposite, in-
verse, parallel, and anti-parallel. According to the calculation
results, the opposite and parallel patterns are the most fa-
vored, while the inverse pattern is almost impossible because
of the torsional strain it imposes on LX. Therefore, a total of
nine possible apportionment patterns, labeled from I to IX,
can be found within a ZIF cage (Figure 4a).

for LX with a longer chain length, more diverse substitution
patterns can be accessed (Figure S24). In general, the results
shown that a shorter linker tends to connect adjacent posi-
tions with parallel ligands because of the length limitation,
while for a longer linker, although with increased freedom and
length, its torsion strain becomes a dominant factor for spatial
distribution, as a result, it prefers a non-distortion pattern and
substitutes two distant opposite ligands (Figure 4, Table S6).
Our results here exemplify the idea of ab initio synthesis with
predictable arrangement of functional groups within MTV-
MOFs, which provides a tool for sequence manipulation in
multi-component materials.
