Porous aromatic frameworks (PAFs) are a fundamental group of porous materials characterized by their distinct structural features and large surface areas. These synthesized from building units linked strong carbon–carbon bonds, which confer exceptional rigidity long-term stability. PAFs functionalities may arise directly the intrinsic chemistry or through postmodification motifs using well-defined chemical processes. Compared to other traditional such as zeolites metallic-organic frameworks, demonstrate superior stability under severe treatments due robust bonding. Even in challenging environments, ease functionalization flexibility specificity. Research on has significantly expanded accelerated over past decade, necessitating comprehensive overview key advancements this field. This review provides an in-depth analysis recent advances synthesis, functionalization, dimensionality PAFs, along with distinctive properties wide-ranging applications. explores innovative methodologies strategies for functionalizing structures, manipulation tailor specific potential Similarly, application areas, including batteries, absorption, sensors, CO2 capture, photo-/electrocatalytic usages, supercapacitors, separation, biomedical discussed detail, highlighting versatility addressing modern scientific industrial challenges.

Abstract This contribution offers a comprehensive overview of methods for forging sp C−Si bonds. Over time, alkynylsilanes (silylacetylenes), once considered mere byproducts hydrosilylation processes, have become essential building blocks in organic synthesis. literature review traces the evolution their synthesis, from traditional methodologies relying on organolithium and organomagnesium compounds to more advanced cross‐coupling reactions involving hydro‐ carbosilanes. Focused primarily past 25 years (2000–2024), it also extensively references significant historical breakthroughs. By analyzing synthetic methodologies, not only survey current state knowledge but identifies areas improvement. Furthermore, emphasize importance 1‐alkynylsilanes (1‐silyl‐1‐alkynes), selected applications these are highlighted, confirming potential

The copper-free Heck–Cassar–Sonogashira (HCS) reaction, known since 1975, nowadays represents one of the most powerful methods for C–C bond formation in organic synthesis with several industrial applications. Despite its great success, mechanism is still under discussion, reported possible pathways. To clarify HCS reaction mechanism, stoichiometric and catalytic reactions were carried out monitored by 31P/1H NMR spectroscopy, HPLC, GC chromatography. In particular, investigation role base, mimicking real conditions, highlighted fact that secondary amines rapidly induce precatalyst reduction decrease energy barrier alkyne carbopalladation step. results supported via direct coordination terminal on oxidative addition complex. Depending palladium counterion, independent solvent, aromatic substitutions, temperature, substitution, these studies support two different pathways: halides, a neutral route, triflate, cationic one.

As global environmental issues become increasingly severe, the overconsumption of traditional energy sources and associated pollution problems have more prominent, creating an urgent need to find cleaner efficient alternative sources. In this context, nuclear energy, as a low-carbon high-efficiency option, has gradually gained widespread attention. With continuous development technology, application expanded globally. However, use also brought about various challenges, particularly in terms waste disposal, radiation safety, risk accidents, which sparked extensive discussions on sustainability energy. Of particular concern is radioactive iodine released during uranium fission reactions, poses significant potential risks human health ecological environment, making removal enrichment issue. To address challenge, porous nanomaterials, with their excellent adsorption properties high surface area, research hotspot recent years shown great for enrichment. This review focuses nanomaterials adsorption, including metal-organic frameworks (MOFs), covalent organic (COFs), polymers (POPs), discusses synthesis methods these materials well practical applications removal. Finally, future trends are envisioned.
