Starburst oxadiazole glasses are obtained by the reaction of aromatic tetrazoles with acid chlorides. The synthesis and thermal properties of these novel compounds are described. One of the glasses—unlike the others, which recrystallize when heated above their glass‐transition temperatures–is stable up to 350°C and is thus the first example of a stable amorphous molecular material with oxadiazole units. Low molecular weight organic compounds that form stable glasses are of interest for applications as photoconductors or light‐emitting devices.
