Synthesis and Characterization of an Azido Nitrofurazanyl Ether: An Energy‐Rich Heterocyclic Plasticizer With a Low Glass Transition Temperature

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT We report on the synthesis and characterization of 3‐(2‐(2‐azidoethoxy)ethoxy)‐4‐nitro‐1,2,5‐oxadiazole (NFPEG2N3), which is a liquid nitrofurazanyl ether that was designed to be an energy‐rich plasticizer for glycidyl azide polymer (GAP)‐ and nitrocellulose (NC)‐based formulations.

Diazo Transfer From Nitrous Oxide Employing Phosphorus Ylides

open access: yesAngewandte Chemie, Volume 138, Issue 22, 25 May 2026.
A phosphorus ylide‐mediated strategy achieves the direct fixation of nitrous oxide (N2O) to access diazo compounds, which after intra‐ or intermolecular trapping, afford N2‐containing organic building blocks. This approach provides an alternative to hazardous diazo‐transfer reagents and establishes N2O fixation as a sustainable methodology.

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

open access: yesSmall Methods, EarlyView.
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.

Unusual backfolded binding poses of BAZ2A bromodomain binders

open access: yesActa Crystallographica Section D, EarlyView.
We identified BAZ2A‐binding compounds assuming a peculiar, almost enclosed, conformation. These molecules pose a basis for the development of potent BAZ2A macrocyclic inhibitors, as performed for other bromodomains.BAZ2A is a large multidomain protein overexpressed in aggressive prostate cancer, where it potentiates migration and invasion of other ...
