基于聚集诱导发光原理研究三苯胺醛-丙二腈复合物的电化学发光效应

基于聚集诱导发光（AIE）原理研究了三苯胺醛-丙二腈（MT）复合物的电化学发光（ECL）效应，成功合成MT复合物，研究其在水/二甲基亚砜（H₂O/DMSO）体系和牛血清蛋白（BSA）体系中的荧光增强效应.MT溶解于不同配比的H₂O/DMSO时，体系中的聚集效果也不同，随着水含量的增加，荧光效应逐步增强，ECL强度也逐步增强.同时，因为BSA本身具有疏水和亲水基团，当BSA与有机物混合时，疏水部分将复合物包裹在一起，限制其分子中基团的振动和转动，通过BSA体系进行聚集诱导能够观察到非常明显的荧光增强效应及ECL增强效应.文章结合聚集诱导效应和ECL，为ECL探针的研究提供了新的思路.

Study on the electrochemiluminescence effect of triphenylamine aldehyde-malonitrile complex based on the principle of aggregation-induced luminescence

The electrochemiluminescence(ECL) of triphenylaldehyde-malononitrile(MT) complex was studied based on the principle of aggregation-induced emission(AIE). In this study, MT complex was successfully synthesized and its fluorescence enhancement effect in water/dimethyl sulfoxide (H₂O/DMSO) system and bovine serum protein(BSA) system was studied. When MT is dissolved in H₂O/DMSO with different ratios, the aggregation effect in the system is different. With the increase of water content, the fluorescence effect is gradually enhanced, resulting in gradually enhancing ECL intensity. Also, because BSA itself has hydrophobic and hydrophilic groups, when BSA is mixed with organic matters, the hydrophobic part will wrap the complex together and limit the vibration and rotation of groups in its molecules. Through aggregation induction of BSA system, a very obvious fluorescence enhancement effect and ECL enhancement effect can be observed. Therefore, the combination of the aggregation induced effect and ECL provides a new idea for the study of ECL probes.
