ChemistryEurope, EarlyView.A modular synthetic approach enables the preparation of azulene‐fused heterocycles via nucleophilic aromatic substitution followed by intramolecular cyclization of alkynyl fluoroazulenes. The method allows the incorporation of various heteroatoms (N, O, S, Se, and Te), leading to structurally diverse heteroannulated azulenes.

Polydopamine‐Mediated Grafting of Cationic Polymer Brushes for Adsorption of Fluorinated Compounds
Chemistry – A European Journal, EarlyView.We introduce a versatile approach to fabricate tunable charged interfaces by functionalizing stonewool fibers with a polydopamine (PDA)–quaternary amine coating via a grafting‐to method. The modified surfaces exhibit rapid, concentration‐dependent adsorption of anionic species driven by electrostatic interactions.
