Glass-forming properties materials

Other structural concepts evolved, one of them being triptycenes (55). Here, additional wings are introduced into the molecules by Diels-Alder type reactions. The glass-forming properties are improved by the propeller-like rigid structure [89]. We end our overview of the different classes of molecular glasses with these materials and note that the number of published structures is growing every year. More details on the different materials can be found in one of the recent chemical reviews [102-104].

Some phosphate glasses have high ionic conductivities, which, combined with their low melting points, simple composition, ease of preparation and strong glass-forming properties, renders them potentially useful as electrical materials [30] (see also Section 12.20).
