Ordered crystalline materials dominate research into both metal-organic frameworks (MOFs) and hybrid organic-inorganic perovskites (HOIPs) [1,2]. They are however a new family of glass-forming materials, in addition to the known inorganic, organic and metallic categories. Here we discuss their response to temperature, and the structural behaviour of the liquids and glasses formed upon melt-quenching [3,4]. We will also see that these ‘soft’ materials exhibit highly unusual properties, not just in terms of their chemistry, but also in terms of their behaviour at extreme conditions [5].
