On October 15, 2020, Yang, Qing-Yu; Zhang, You-Ming; Ma, Xiao-Qiang; Dong, Hong-Qiang; Zhang, Yun-Fei; Guan, Wen-Li; Yao, Hong; Wei, Tai-Bao; Lin, Qi published an article.HPLC of Formula: 150-78-7 The title of the article was A pillar[5]arene-based fluorescent sensor for sensitive detection of L-Met through a dual-site collaborative mechanism. And the article contained the following:
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. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).HPLC of Formula: 150-78-7
