TA-TEMPO 共价有机框架实现室温 7Li 量子传感
Quantum Sensing of Lithium Ions with Defect-Engineered Recognition Pockets in a TEMPO-Modified Covalent Organic Framework
AI 导读
研究报道了 TA-TEMPO 共价有机框架，其中稀释的氮氧自由基与 Li+ 结合的三嗪基元构成缺陷工程识别口袋，用于室温 7Li 传感。在 LiBr 的四氢呋喃溶液中，该材料对 Li+ 的检测灵敏度为 1.0 × 10–4 mol·L–1，较此前基准提升 50 倍，并可覆盖多种锂基电解质。
推荐理由
TA-TEMPO 把三嗪锂结合位点与稀释氮氧自由基共置于同一共价有机框架中，读者可看到识别口袋如何同时服务于选择性与相干自旋读出。
创新点
将稀释氮氧自由基与三嗪 Li+ 结合位点集成在同一共价有机框架中形成识别口袋，在保持自旋相干性的同时把目标核素拉进超精细检测体积，使灵敏度与选择性由化学识别而非单纯提高自由基浓度来实现。
