Poly(1,3,4-oxadiazoles) via aromatic nucleophilic displacement [PDF]

open access: yes, 1992
Poly(1,3,4-oxadiazoles) (POX) are prepared by the aromatic nucleophilic displacement reaction of di(hydroxyphenyl) 1,3,4-oxadiazole monomers with activated aromatic dihalides or activated aromatic dinitro compounds. The polymerizations are carried out in

A survey of liquid crystalline oxadiazoles

open access: yes, 2008
We propose a survey of those oxadiazole compounds, which are mesogenic. We will see that they can have bend-shaped molecules, a biaxial nematic phase, or other interesting peculiarities in the nematic and smectic phase.

Decoding Urease Inhibition: A Comprehensive Review of Inhibitor Scaffolds

open access: yesChemMedChem, Volume 21, Issue 2, January 2026.
Representative functional groups known for urease inhibition are reviewed within diverse scaffolds using structure–activity analyses to identify features associated with high inhibitory activity. Urease is a metalloenzyme produced by a wide range of organisms and plays a critical role in nitrogen microbial metabolism by catalyzing the hydrolysis of ...
