摘要: 碳化聚合物点因其可调的发光性能和简便的合成方法，已成为有前景的室温磷光材料。然而，当前依赖氢键/共价键来增强发光的策略存在磷光强度有限和颜色多样性不足(主要为绿色)的问题。本工作提出构建离子键交联网络作为一种新颖的设计策略来解决这些局限性。得益于离子键的高强度、无方向性和无饱和性，构建的交联网络能够固定发色团并抑制非辐射跃迁。通过将锂离子引入聚丙烯酸基碳化聚合物点中，光致发光量子产率从1.1%显著提升至48.4%，磷光强度增强了近40倍。进一步引入锌离子，通过过渡金属掺杂实现了从绿色到黄色的可调谐室温磷光发射。该策略实现了对碳化聚合物点中室温磷光强度和波长的有效调控，为设计具有定制化室温磷光特性的先进有机磷光材料提供了一个通用平台。

Abstract: Carbonized polymer dots (CPDs) have emerged as promising room temperature phosphorescent (RTP) materials owing to their tunable luminescence and facile synthesis. However, current strategies relying on hydrogen/covalent bond for luminescence enhancement suffer from limited phosphorescence intensity, and color diversity (primarily green). This work proposes constructing ionic-bond crosslinked network as a novel design strategy to address these limitations. Owing to the high strength, non-directionality and non-saturation of ionic bond, crosslinked networks are constructed to immobilize chromophores and suppress non-radiative transitions. By incorporating lithium ions into poly(acrylic acid)-based CPDs, the photoluminescence quantum yield is dramatically enhanced from 1.1% to 48.4%, with a 40-fold increase in phosphorescence intensity. Further introduction of zinc ions enables tunable RTP emission from green to yellow via transition metal doping. This strategy achieves effective regulation of RTP intensity and wavelength in CPDs, providing a versatile platform for designing advanced organic phosphorescent materials with tailored RTP properties.
