Poly‐1,3,4‐oxadiazoles. I. Polyphenylene‐1,3,4‐oxadiazoles

Journal of Polymer Science Part A: General Papers, 1965
AbstractPolyphenylene‐1,3,4‐oxadiazoles have been prepared from benzenedicarboxylic acids or their derivatives and hydrazine by solution polycondensation in fuming sulfuric acid or polyphosphoric acid. These polymers were characterized by good thermal stability, and the molecular weights attained were high enough for the products to exhibit fiber‐or ...

1,3,4-Oxadiazole Bridges: A Strategy to Improve Energetics at the Molecular Level.

Angewandte Chemie, 2020
Many energetic materials synthesized to date have limited applications because of low thermal and/or mechanical stability. This limitation can be overcome by introducing structural modifications such as a bridging group.

Banana-shaped 1,2,4-oxadiazoles

Pramana, 2003
3,5-Disubstituted 1,2,4-oxadiazoles are a new type of liquid crystalline (LC) compounds with asymmetrical five-membered heterocycle as a central unit. They have a bent shape and are very convenient model-compounds for studying the dependence of the LC properties on the molecular design.

Oxadiazoles in Medicinal Chemistry

Journal of Medicinal Chemistry, 2012
Oxadiazoles are five-membered heteroaromatic rings containing two carbons, two nitrogens, and one oxygen atom, and they exist in different regioisomeric forms. Oxadiazoles are frequently occurring motifs in druglike molecules, and they are often used with the intention of being bioisosteric replacements for ester and amide functionalities.
