Energetic polynitro anions, such as dinitramide ion [N(NO2)2–], have attracted significant interest in the field of energetic materials due to their high densities and rich oxygen contents; however, most them usually suffer from low stability. Conveniently stabilizing anions develop new energy well tuning properties still represent challenges. To address these challenges, we herein propose a novel strategy that are encapsulated within cationic metal–organic frameworks (MOFs). We present...
Background Idiopathic pulmonary arterial hypertension (IPAH) is a rare disease with high heritability. Although several predisposing genes have been linked to IPAH, the genetic aetiology remains unknown for large number of IPAH cases. Methods We conducted an exome-wide gene-based burden analysis on two independent case–control studies, including total 331 cases and 10 508 controls. Functional assessments were analyse effects mutations protein biosynthesis function. Results The gene encoding...
A highly diastereoselective reductive Mannich coupling of ketimines and α,β-unsaturated esters was developed using CuOAc−PPh3 or CuOAc−MePPh2 complex as a catalyst (5 mol %) pinacolborane reducing reagent. The reaction easily conducted at room temperature, the substrate generality broad. This platform methodology extended to first catalytic asymmetric CuOAc−DIFLUORPHOS (10 %). Switching reagent from (EtO)3SiH key inducing high enantioselectivity (82−93% ee). High diastereoselectivity also...
Understanding the structure–property relationship in a material is of great importance materials science. To study effect ligand backbones and anionic groups on properties energetic cationic metal–organic frameworks (CMOFs) to disclose their relationships, we designed synthesized series CMOFs based either 4,4′-bi-1,2,4-triazole (btrz) or its azo analogous, 4,4′-azo-1,2,4-triazole (atrz) as ligand, perchlorate [ClO4–] nitroformate [C(NO2)3–, NF–] anion extra-framework anion. Surprisingly,...

Owing unique nitrogen‐rich composition azolates, demonstrate significant potential high‐energy‐density materials....
Fluorine- and oxygen-rich compounds are promising as energetic materials for composite propellants, explosives, pyrotechnics. As an effective timesaving tool screening the structures of potential compounds, computer simulation has been widely used to predict detonation or physicochemical properties molecules with relatively high precision.

High-density materials have attracted extensive attention because of their broad applications. However, strategies for improving the densities MOFs and preparing denser remain almost unexplored. Herein, we propose a tandem anion-ligand exchange strategy synthesizing by using three-dimensional cationic (3D CMOFs) with pillared layered structures as precursors high-density anions small monotopic ligands exogenous guests. By means this strategy, choose nitroformate ion [C(NO2)3-] an anion water...
Polymorphic transition from a metastable phase to stable often occurs in metal-organic frameworks (MOFs) under the action of external stimuli. However, these transitions sometimes result deteriorating their special performances and can even lead serious safety problems. Therefore, developing simple efficient strategy for enhancing stabilities MOF polymorphs is very imperative meaningful. Herein, we propose graphene oxide (GO)-encapsulating improving polymorphs. To illustrate this strategy,...
Organic anions possess various functional properties; however, their presence in wastewater causes environmental pollution. Thus, coupling the separation of such species with resultant function could be highly desirable. Herein, we propose a "killing two birds one stone" strategy for efficient organic pollutant from water at room temperature through direct construction cationic metal-organic frameworks (CMOFs) based on as charge-balancing anions. To illustrate this strategy,...

Fused compounds, a unique class of large conjugate structures, have emerged as prime candidates over traditional nitrogen-rich mono-ring or poly-ring materials. Meanwhile, compounds containing catenated nitrogen chains also attracted attention from scientists due to their high heats formation. On the other hand, azoxy [-N[double bond, length m-dash]N(O)-] moiety has been found increase density effectively in molecular structure compounds. Therefore, combining fused heterocyclic organic...
