A neg.-charged tetraphenylethylene derivative (TPE-SE) was designed and synthesized as turn-on fluorescent sensor for berberine chloride (BBC) detection in aqueous solution The fluorescent property and detection mechanism were elucidated by UV-vis absorption spectra, photoluminescence spectra, dynamic light scattering experiments The results reveal that the BBC can lead to aggregation-induced emission of TPE-SE due to the electrostatic interactions, endowing TPE-SE with excellent turn-on detecting ability, high selectivity and sensitivity to BBC. The detection limit is as low as 6.58 x 10-6M. These results should be applicable to fabricate special turn-on fluorescent sensors towards various antibiotics, and it is crucially important for achieving reasonable control and intake of small biomols. In the experiment, the researchers used many compounds, for example, 9,10-Dimethoxy-5,6-dihydro-[1,3]dioxolo[4,5-g]isoquinolino[3,2-a]isoquinolin-7-ium (cas: 2086-83-1HPLC of Formula: 2086-83-1).
9,10-Dimethoxy-5,6-dihydro-[1,3]dioxolo[4,5-g]isoquinolino[3,2-a]isoquinolin-7-ium (cas: 2086-83-1) belongs to isoquinoline derivatives. Quinoline and isoquinoline skeletons are among the most attractive frameworks with a wide range of biological and pharmacological activities. Most traditional methods of generating isoquinoline do so via oxidative aromatization of dihydro- or tetrahydro-isoquinolines, usually offering some environmental or economic advantage.HPLC of Formula: 2086-83-1
