titleOfInvention |
Preparation and application of an amphiphilic bisbenzimidazole derivative and its supramolecular sensor |
abstract |
The invention provides an amphiphilic bisbenzimidazole derivative BBI, which takes the amphiphilic bisbenzimidazole derivative BBI as a guest and a water-soluble column [5] arene derivative WP5 as the main body. A stable supramolecular sensor BBI- WP5 was formed by self-assembly at a molar ratio of The fluorescence of WP5 is turned on and emits bright blue fluorescence with a minimum detection limit of 5.7×10 ‑8 M, which realizes the specific and selective identification of Pb 2+ in pure water phase. |
