5-(3-Hydroxyphenyl)-1,3,4-oxadiazole-2(3H)-thione hemihydrate

IUCrData, 2019
The title 1,3,4-oxadiazole derivative crystallizes as a hemihydrate, C8H6N2O2S·0.5H2O, with the water molecule located on a twofold rotation axis. The 1,3,4-oxadiazole molecule is essentially planar, the r.m.s. deviation of the non-H atoms being 0.0443 Å.

Binary‐Solvent‐Programmed Single‐Step Inkjet Printing of Self‐Confined Micro‐Inlaid OLED Arrays

Small Methods, Volume 10, Issue 14, 22 July 2026.
Solvent‐programmed micro‐inlay inkjet printing enables lithography‐free, high‐resolution μ‐OLED arrays in a single step. A thermodynamically tuned 3:1 (w/w) chloroform/dichloroethane blend not only drives interfacial phase separation between the solute and polymers but also stabilizes droplet ejection, forming rim‐confined emissive domains in one pass.
