Abstract: Combining high recognition selectivity with excellent electrochemiluminescent (ECL) performance, the imprinted poly(luminol-p-aminothiophenol) was prepared by the electrochemical copolymerization of luminol and p-aminothiophenol onto the gold electrode surface in the presence of triazophos. The recognition selectivity and ECL of the imprinted poly(luminol-p-aminothiophenol) were studied using triazophos as analyte. It was found that the imprinted poly(luminol-p-aminothiophenol) presented better ECL emission to triazophos than that of the polyluminol. On this basis, a reagentless ECL sensor based on the imprinted poly(luminol-p-aminothiophenol) as recognition elements is established for the detection of ultra-trace triazophos residues in the environmental water samples under near neutral condition. The resulting reagentless ECL sensor shows wide linear ranges from 1.0 × 10-10 to 1.0 × 10-6 M with lower detection limit of 5.8 × 10-11 M for triazophos
