“…As shown in Figure F, the stretching vibrations of N–H, CN, and C–N (2788, 1620, and 1457 cm –1 in BIM) are still present in BIM/TOAB, indicating that BIM exists in BIM/TOAB without hydrogen bonding interactions, which is further demonstrated in UV–vis spectra (Figure S3). − In addition, new characteristic peaks located at 2852 and 2922 cm –1 are observed in BIM/TOAB, which are attributed to the symmetric and asymmetric stretching vibrations of −CH 2 and −CH 3 in the carbon chain in TOAB . Based on the above results, we believe that BIM is adsorbed on the hydrophobic chain of TOAB in BIM/TOAB.…”

Exploring the depolymerization strategy of liposoluble luminophores in the aqueous phase is vital for the development of electrochemiluminescence (ECL). In this work, tetraoctylammonium bromide (TOAB) with four long hydrophobic chains and short hydrophilic ends is used as a template to limit the aggregation of benzimidazole (BIM). By adjusting the loading of BIM on the hydrophobic chains of TOAB, a two-dimensional lamellar BIM/TOAB is formed, the ECL intensity of which is 6.4 times higher than that of the aggregated BIM (H 2 O 2 as the coreactant). In terms of ECL spectroscopies, cyclic voltammetry , ECL transients, and the adjustment of the scanning potential range, the ECL mechanism is thoroughly studied. This work provides a new way to depolymerize organic luminophores and reveals a possible pathway in the annihilation ECL mechanism.

“…As shown in Figure 1F, in the spectrum of BIM, the peaks at 1620 and 1478 cm −1 assigned to the C�N and C−N stretching vibration, respectively. 21,22 However, the ν(C�N) and ν(C−N) shifts gave lower wave numbers (1607 and 1456 cm −1 ) in CoBIM and CoBIM/CTAB, indicating that BIM was coordinated to Co 2+ through the Co−N bond. It is worth noting that the characteristic peaks of CoBIM and CoBIM/ CTAB were almost identical, suggesting that CTAB did not affect the coordination of Co 2+ and BIM, but only acted as a surfactant to assist the construction of the confined coordination spaces to limit the growth of CoBIM/CTAB nanoparticles.…”

Selective and sensitive detection of nitrite has important medical and biological implications. In the present work, to obtain an enhanced electrochemiluminescence (ECL) determination of nitrite, a novel nano-ECL emitter CoBIM/ cetyltrimethylammonium bromide (CTAB) was prepared via a micelle−assisted, energy-saving, and ecofriendly method based on benzimidazole (BIM) and CTAB. Unlike conventional micelle assistance, the deprotonated BIM (BIM − ) preferential placement was in the palisade layer of cationic CTAB-based micelles. Enriching the original CTAB micelle with BIM − disrupted its stability and resulted in the formation of considerably smaller BIM/CTAB-based micelles, providing a confined coordination environment for BIM − and Co 2+ . As a result, the growth of CoBIM/CTAB was also limited. Owing to the unusual nitration reaction between BIM and nitrite, the prepared CoBIM/CTAB was successfully applied as a novel ECL probe for the detection of nitrite with a wide linear range of 1−1500 μM and a low detection limit of 0.67 μM. This work also provides a promising ECL platform for ultrasensitive monitoring of nitrite and it was applied with sausages and pickled vegetables.

“…According to the calculations of Chesketch software, the length and the width of the ABIM molecule are, respectively, 0.73 nm and 0.50 nm. 32 By assuming that the distance between two ABIM molecules is about 0.30 nm, a bilayer arrangement of ABIM molecules in the interlayer space is possible with a tilt angle of about 50°, as described by the scheme shown in Fig. 5.…”
