L-Methionine (L-Met) is one of the essential amino acids in human health, efficiently detect L-Met is a significant issue. Herein, a concept “”dual-site collaborative recognition”” had been successfully introduced into the design and achieved high selective and sensitive recognition of L-Met. In order to realize the “”dual-site collaborative recognition””, the authors rationally designed and synthesized an ester functionalized pillar[5]arene-based fluorescent sensor (SP5). And it shows blue Aggregation-induced emission (AIE) fluorescence. In the SP5, the pillar[5]arene group act as C-H···π interactions site, and ester group serve as multi hydrogen bonding acceptor. The SP5 exhibited high selectivity and sensitivity (2.84 × 10-8 M) towards L-Met based on the collaboration of electron-rich cavernous pillar[5]arene group and ester group through C-H···π and H-bond interactions, resp. This “”dual-site collaborative recognition”” mechanism has been studied by 1H NMR, ESI-MS and theor. calculation including frontier orbital (HOMO and LUMO), electrostatic potential (ESP) and the noncovalent interaction (NCI). These theor. calculations not only support the proposed host-guest recognition mechanism, but also provided visualized information on the “”dual-site collaborative recognition”” mode. Furthermore, the concept “”dual-site collaborative recognition”” is an effective strategy for easily detecting biol. mols. In the experimental materials used by the author, we found 1,6-Dibromohexane(cas: 629-03-8HPLC of Formula: 629-03-8)
1,6-Dibromohexane(cas: 629-03-8) is generally used to introduce C6 spacer in the molecular architecture. Some of the examples are: synthesis of solvent processable and conductive polyfluorene ionomers for alkaline fuel cell applications; synthesis of cross-linkable regioregular poly(3-(5-hexenyl)thiophene) (P3HNT) for stabilizing the film morphology in polymer photovoltaic cells.HPLC of Formula: 629-03-8
