Abstract

A pronounced enthalpy release occurs around 1.38Tg in the prototypical metal–organic framework glass formed from ZIF-4 [Zn(C3H3N2)2], but there is no sign for any crystallization (i.e., long-range ordering) taking place. The enthalpy release peak is attributed to pore collapse and structural densification.
