Abstract

Covalent organic frameworks (COFs) are crystalline, porous polymers with tunable architectures, high surface areas, and robust chemical stability, making them promising platforms for chemical sensing. This review surveys recent advances in luminescent COFs (LCOFs) for the selective detection of hazardous contaminants via fluorescence-based mechanisms, including photo-induced electron transfer and energy transfer. Representative studies discuss ultra-low detection limits for UO₂²⁺, Hg²⁺, and Pb²⁺, along with rapid response times, high adsorption capacities, and strong recyclability. Sensitivity and selectivity are further enhanced through functionalization strategies such as amidoxime grafting, lanthanide incorporation, and linkage engineering. Beyond actinide sensing, LCOFs have demonstrated effectiveness toward mercury, lead, nitro-aromatic explosives, and biological markers, underscoring their functional versatility. Despite these advances, key challenges persist, including scalable synthesis, structural stability in complex matrices, and integration into deployable sensing devices. Future progress leveraging hybrid material systems, computation-guided design, and portable detection platforms could position LCOFs as transformative tools for environmental monitoring, nuclear safety, and public health protection.

COFs在行动：监测环境污染物中铀、汞、铅和硝基化合物的先进方法。

共价有机框架（COFs）是晶体多孔聚合物，具有可调的结构，高表面积和强大的化学稳定性，使其成为化学传感的有前途的平台。本文综述了利用荧光机制（包括光诱导电子转移和能量转移）选择性检测有害污染物的发光COFs （LCOFs）的最新进展。代表性研究讨论了UO22+、Hg2+和Pb2+的超低检出限，响应时间快，吸附能力高，可回收性强。通过偕胺肟接枝、镧系元素掺入和连锁工程等功能化策略，进一步提高了灵敏度和选择性。除了锕系元素传感外，LCOFs已经证明了对汞，铅，硝基芳香炸药和生物标记物的有效性，强调了其功能的多功能性。尽管取得了这些进步，但关键的挑战仍然存在，包括可扩展的合成、复杂矩阵的结构稳定性以及集成到可部署的传感设备中。利用混合材料系统、计算引导设计和便携式检测平台的未来进展，可以将LCOFs定位为环境监测、核安全和公共卫生保护的变革性工具。
