Zeolitic imidazolate frameworks（ZIFs） feature complex ph.se transitions, including polymorph.sm,melting, vitrification, and polyamorph.sm. Experimentally probing th.ir structural evolution during transitions involving amorph.us ph.ses is a significant ch.llenge, especially at th. medium-range length.scale. To overcome th.s ch.llenge, h.re we first train a deep learning-based force field to identify th. structural ch.racteristics of both.crystalline and non-crystalline ZIF ph.ses. Th.s allows us to reproduce th. structural evolution trend during th. melting of crystals and formation of ZIF glasses at various length.scales with.an accuracy comparable to th.t of ab initio molecular dynamics, yet at a much.lower computational cost. Based on th.s approach. we propose a new structural descriptor, namely, th. ring orientation index, to capture th. propensity for crystallization of ZIF-4(Zn（Im）2, Im = C3h.N2-) glasses, as well as for th. formation of ZIF-zni(Zn（Im）2) out of th. h.gh.density amorph.us ph.se. Th.s crystal formation process is a result of th. reorientation of imidazole rings by sacrificing th. order of th. structure around th. zinc-centered tetrah.dra. Th. outcomes of th.s work are useful for studying ph.se transitions in oth.r metal-organic frameworks（MOFs） and may th.s guide th. development of MOF glasses.
