abstract = {The ability to crosslink Metal-Organic Frameworks (MOFs)
has recently been discovered as a flexible approach towards
synthesizing MOF-templated “ideal network polymers”.
Crosslinking MOFs with rigid cross-linkers would allow the
synthesis of crystalline Covalent-Organic Frameworks (COFs)
of so far unprecedented flexibility in network topologies,
far exceeding the conventional direct COF synthesis
approach. However, to date only flexible cross-linkers were
used in the MOF crosslinking approach, since a rigid
cross-linker would require an ideal fit between the MOF
structure and the cross-linker, which is experimentally
extremely challenging, making in silico design mandatory.
Here, we present an effective geometric method to find an
ideal MOF cross-linker pair by employing a high-throughput
screening approach. The algorithm considers distances,
angles, and arbitrary rotations to optimally match the
cross-linker inside the MOF structures. In a second,
independent step, using Molecular Dynamics (MD) simulations
we quantitatively confirmed all matches provided by the
screening. Our approach thus provides a robust and powerful
method to identify ideal MOF/Cross-linker combinations,
which helped to identify several MOF-to-COF candidate
structures by starting from suitable libraries. The
algorithms presented here can be extended to other advanced
network structures, such as mechanically interlocked
materials or molecular weaving and knots.},
