Since its birth in 1967, the utilization of chemiluminescence resonance energy transfer (CRET) has made substantial progress in a variety of fields for its unique features. However, the quantitative relationship between CRET efficiency and donor-acceptor distance has not yet been determined owing to the difficulty in designing the variable lengths between chemiluminescent donors and acceptors. Herein, we synthesized three kinds of tetraphenylethene (TPE)-anchored cationic surfactants with aggregation-induced emission (AIE) characteristics. For the first time, it is quantitatively demonstrated that the CRET efficiency is inversely proportional to the sixth power of distance between luminol donors and TPE acceptors. The details disclosed in this contribute have provided the solid evidence that CRET follows Förster resonance theory. Our strategy would build a promising platform to control donor-acceptor distance, allowing to the interdisciplinary applications of CRET.
自 1967 年诞生以来，由于其独特的性质，化学发光共振能量转移（CRET）在许多领域的应用都取得了实质性的进展。然而，由于难以设计化学发光供体和受体之间的可变长度，CRET 效率与供体-受体距离之间的定量关系尚未确定。在这里，我们合成了三种具有聚集诱导发射（AIE）特性的四苯乙烯（TPE）锚定阳离子表面活性剂。首次定量证明，CRET 效率与鲁米诺供体和 TPE 受体之间的距离的六次方成反比。本研究中揭示的细节为 CRET 遵循福斯特共振理论提供了确凿的证据。我们的策略将为控制供体-受体距离建立一个有前途的平台，允许 CRET 在多个学科的应用。
