Used in the synthesis of conjugated porous organic polymers for applications in gas storage and separation, particularly effective in capturing carbon dioxide due to its high surface area and tailored pore environment. Also employed in optoelectronic devices as a scaffold for light-harvesting materials, leveraging its extended π-conjugation system to enhance charge transport. Shows promise in catalysis support, where its rigid framework stabilizes metal nanoparticles or catalytic sites. Additionally, explored in sensing platforms for detecting aromatic pollutants through fluorescence quenching mechanisms. Features multiple aldehyde groups, enabling efficient reactions with amines or hydroxyl-containing compounds to form stable covalent bonds in polymer networks.
