To further the ideas in this study, we are working towards embedding the pore structures of extended network materials such as metal-organic frameworks (MOFs) into a lowdimensional latent space. MOFs are more tunable materials than porous cages, as exemplified by the tens of thousands of MOFs that have been reported in comparison to the hundreds of porous cage solids; 20 thus, MOFs exhibit a greater diversity in their void space architectures. However, MOFs present a more formidable challenge than porous organic cage molecules because their 3D porosity images are periodic with varying Bravais lattices.
