“…Therefore, it is urgent to construct a simple and effective way to improve the ECL performance of the TPE at the cathode. It has been proved that the property of solvents is crucial to the aggregation process of AIE materials, and solvent regulation could be regarded as a vital way to improve the AIE performance, which has been reported in fluorescence. − Similar to the study on fluorescent AIE materials, we have preliminarily confirmed that solvent regulation is also effective in modulating the ECL performance of AIECL materials such as anodic TPE . Consequently, we attempt to modulate cathodic AIECL including the ECL intensity, stability, and wavelength of TPE via directly adjusting the solvent in the AIE process.…”

Zearalenone (ZEN) is an extremely hazardous chemical widely existing in cereals, and its high-sensitivity detection possesses significant significance to human health. Here, the cathodic aggregation-induced electrochemiluminescence (AIECL) performance of tetraphenylethylene nanoaggregates (TPE NAs) was modulated by solvent regulation, based on which an electrochemiluminescence (ECL) aptasensor was constructed for sensitive detection of ZEN. The aggregation state and AIECL of TPE NAs were directly and simply controlled by adjusting the type of organic solvent and the fraction of water, which solved the current shortcomings of low strength and weak stability of the cathode ECL signal for TPE. Impressively, in a tetrahydrofuran–water mixed solution (volume ratio, 6:4), the relative ECL efficiency of TPE NAs reached 16.03%, which was 9.2 times that in pure water conditions, and the maximum ECL spectral wavelength was obviously red-shifted to 617 nm. In addition, “H”-shape DNA structure-mediated dual-catalyzed hairpin self-assembly (H-D-CHA) with higher efficiency by the synergistic effect between the two CHA reactions was utilized to construct a sensitive ECL aptasensor for ZEN analysis with a low detection limit of 0.362 fg/mL. In conclusion, solvent regulation was a simple and efficient method for improving the performance of AIECL materials, and the proposed ECL aptasensor had great potential for ZEN monitoring in food safety.

Since aggregation‐induced electrochemiluminescence (AIECL) luminophore overcomes the restriction of aggregation‐caused quenching in solid luminescent materials, AIECL luminophore has become a promising material in the field of electrochemiluminescence (ECL) engineering. However, the lack of ECL emitters with high AIECL performance limits its wide application. Herein, imine‐linked covalent organic frameworks (COFs) with C4 symmetrical tetraphenyl ethylene and C2 symmetrical five‐membered heteroaromatic monomers are designed as ECL emitter in aqueous media. Significantly, the ECL intensity of COFs with terthienyl units (TTA‐TAPE) is 206 times that of COFs with furan units in the presence of tri‐n‐propylamine (TPrA), which is the result of enhancing ECL signals by increasing the thiophene units and π‐π conjugation of COFs. Furthermore, the ECL mechanism of these COFs is vested in the bandgap model. Thus, the study provides a strategy for designing highly efficient ECL‐active COFs emitters with excellent AIECL efficiency.
