Water-soluble conjugated polymers (WSCPs), distinguished by their unique optoelectronic properties and water solubility, have found versatile applications. Despite the fact that pyrazine its fused ring serve as pivotal building blocks in high-performance polymers, exploration of WSCPs incorporating a backbone has been limited due to synthetic challenges. Herein, we developed new strategy with synchronized construction polymerization can transform vinyl azides into cores under metal-free open-to-air conditions. Employing this approach, designed prepared series novel pyrazine-based good solubility fluorescence properties. Remarkably, photoluminescence intensity free carboxyl groups surpassed featuring ester groups. Single crystal X-ray diffraction analysis DFT calculations indicated enhancement could be attributed presence rings polymer backbone, facilitating formation intermolecular hydrogen bonds. These interactions effectively restrict vibrational relaxation minimize loss energy via nonradiative decay pathways, ultimately resulting higher emission intensity.
