Abstract

Abstract A planar bis(1,3,4-oxadiazole) bridging strategy was developed to access rigid, extended-conjugated tetracyclic energetic compounds. Incorporation of this bridge into two distinct energetic scaffolds afforded 4 and 7. Single-crystal X-ray diffraction revealed a nearly planar bis(1,3,4-oxadiazole) bridge in both compounds, accompanied by extended π-electron delocalization across the molecular frameworks. Compound 4 showed enhanced thermal and mechanical stability, while 7 combined improved energetic performance with increased stability.

平面双（1,3,4-恶二唑）桥接高能量低灵敏度四环化合物

摘要建立了一种平面双（1,3,4-恶二唑）桥接策略，以获得刚性、扩展共轭的四环含能化合物。将这座桥结合成两个不同的能量支架，提供了4和7。单晶x射线衍射显示，两种化合物均存在近平面的双（1,3,4-恶二唑）桥，并伴有跨分子框架的扩展π电子离域。化合物4表现出增强的热稳定性和机械稳定性，而化合物7表现出增强的能量性能和增强的稳定性。

期刊介绍： Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
