Abstract:
Herein, four novel tetraphenylethylene-embedded mononuclear ruthenium complex matrices were synthesized by connecting the tetraphenylene framework with 2,2':6',2″-terpyridine ruthenium complex fragment. They exhibited excellent dual-emitting electrochemiluminescence (ECL) properties at both the cathode and anode. Among them, DTM1 serves as a solid-state ECL probe. Covalent organic frameworks (COFs) are used as the enrichment-immobilization carrier for the probe. Further, the molecular imprinted ECL sensor based on DTM1@PA-COFs was constructed to detect kanamycin (KANA). Under the optimal conditions, the sensor displayed a good linear relationship between the ECL intensity and the logarithm of KANA concentration within the range of 1 × 10-17 M - 1 × 10-10 M. The detection limit was as low as 9.4 × 10-18 M. Moreover, the sensor was used for detecting KANA in pork, chicken, and milk samples with excellent recoveries. This study not only provides ideas for designing new dual-emitting ECL probes but also offers a novel approach for ultrasensitive antibiotic detection.
