Abstract:
Chemiluminescence resonance energy transfer (CRET) efficiency can be enhanced by confining CRET donors and acceptors within nanoscale spaces. However, this enhanced efficiency is often affected by uncertainties stemming from the random distribution of CRET donors and acceptors in such confined environments. In this study, a novel confined nanospace was created through the surfactant modification of carbon dots (CDs) exhibiting aggregation-induced emission (AIE) characteristics. Hydrophobic CRET donors could be effectively confined within this nanospace. The distance between the CRET donors and acceptors could be controlled by anchoring the AIE-CDs as the CRET acceptors, resulting in significantly improved CRET efficiency. Furthermore, this AIE-CDs-based CRET system was successfully applied to the detection of hydrogen peroxide (H2O2) in rainwater, showcasing its potential for practical applications.
摘要:
化学发光共振能量转移(CRET)效率可以通过将CRET供体和受体限制在纳米级空间中来提高。然而,这种提高的效率通常受到在这种受限环境中CRET供体和受体随机分布所产生的不确定性的影响.在这项研究中,通过对具有聚集诱导发射(AIE)特征的碳点(CD)的表面活性剂改性,产生了一种新型的受限纳米空间。疏水性CRET供体可以有效地限制在该纳米空间内。CRET供体和受体之间的距离可以通过锚定AIE-CD作为CRET受体来控制,显著提高了CRET效率。此外,这种基于AIE-CD的CRET系统已成功应用于雨水中过氧化氢(H2O2)的检测,展示其实际应用的潜力。
