The Application For Aggregation Induced Emission On Chemiluminescence And Detection Of Micelle Formation Process

The emergence of aggregation-induced emission (AIE) has opened up a new avenue for scientists. Compared with the conventional fluorescent dyes, AIE effect can boost the fluorescent intensities and fluorescent quantum yields when aggregated in concentrated solutions. The emergence of AIE can sweep away the shortcomings of aggregation caused quenching (ACQ). To date, a variety of fluorogens with AIE characteristics have attracted widespread interest as a multifunctional platform for various applications in chemical sensors, biological imaging, and optoelectronic devices. Therefore, we investigated the influence of AIE on the chemiluminescence (CL) emissions and the detection of micelle formation. The main research content is as follows: (1) We selected gold nanoclusters, Au(I)-thiolate complexes and 9,10-bis[4-(3-sulfonatopropoxyl)-styryl]-anthracene (BSPSA) as model AIE molecules to reveal the role of AIE molecules on the bis(2,4,6-trichlorophenyl) oxalate (TCPO)-H2O2 CL system. It is found that these AIE molecules with an increase in the degree of aggregation exhibit remarkably enhanced performances toward the CL signals of the TCPO-H2O2 system. To gain further insight into AIE structure-property relationships in chemiluminescence resonance energy transfer (CRET) behavior, we have comprehensively explored the structural, optical, and CL properties. With respect to the experimental observations, we concluded unambiguously that the common natures of these AIE molecules are pivotal to improve the current CRET efficiency. Our success should inspire more exciting research in the development of other CL systems-based AIE molecules.(2) TPE units were incorporated into sodium dodecyl sulfonate (SDS) molecules to generate luminescent surfactant (denoted as TPE-SDS) with AIE characteristics. Because of the long hydrophobic chain structure, TPE-SDS is easy aggregated through hydrophobic force and showing strong fluorescence intensity. TPE-SDS fluorescence probe could be used in detecting the premicelle and CMC (critical micelle concentration) of anionic, cationic and nonionic surfactants. However, to the best of our knowledge, it is our primary interest to investigate the formation process of micelle by AIE surfactant probe. Our success provided a new method and basis for the premicelle and CMC detection.
