Imidazole‐Linked Covalent Organic Polymers: Sustainable Materials for Greenhouse Gas Capture, Iodine Vapor Adsorption, and CO 2 Cycloaddition

Noorullah Baig, Hassan Hasan Hammud, Suchetha Shetty, Badvel Pallavi et autres

Addressing the dual challenges of radioiodine pollution and rising CO 2 emissions, we report a series of five robust imidazole‐based covalent organic polymers ( iCOP1–5 ) synthesized via a microwave‐assisted, one‐pot [3 + 2] cyclopentannulation reaction. The design strategy leverages a nitrogen‐rich …

and a detection limit of 0.756 µM. Time-resolved fluorescence lifetime measurements strongly support the proposed quenching mechanism, indicating that PA is sensed through a combination of static (ground-state ion-pair/charge-transfer) and dynamic (collisional, PET-driven) quenching, consistent with the upward-curving Stern-Volmer plot and the …

Synthesis, characterization and cytotoxicity properties of new dichlorothiophene based nicotinonitrile derivatives

Eman Al-Masri, Basem F. Ali, Mahmoud Al‐Refai, Lubna Salah et autres

New pyridine-carbonitrile derivatives ( 1–16 ) were synthesized and characterized. Some of these derivatives, ( 7–9 ) and ( 15–16 ), were formed as minor products by decyanation of the corresponding pyridine-carbonitriles main product. By using various spectral techniques, IR, 1 H …
